This paper discusse four new Takagi-Sugeno fuzzy controllers (T-S FCs) for the longitudinal slip control of an Antilock Braking System laboratory equipment. Two discrete-time dynamic Takagi-Sugeno fuzzy models of the controlled plant are derived based on the parameters in the consequents of the rules using the domains of the input variables, and doing the local linearization of the plant model. The original T-S FCs are designed by parallel distributed compensation to obtain the state feedback gain matrices in the consequents of the rules. Two T-S FCs are tuned by imposing relaxed stability conditions to the fuzzy control systems (FCSs) and the other two T-S FCs are tuned by the linear-quadratic regulator approach applied to each rule. Linear matrix inequalities are solved to guarantee the global stability of the FCSs. Real-time experimental results validate the original T-S FCs and design approaches.

Operators' intelligent and skillful decisions are necessary for the teleoperation of a mobile robot when there are many scattered obstacles. Among the sensors used for environment recognition, the camera is the most popular and powerful. However, there are several limitations in the camera-based teleoperation of a mobile robot. For example, shadowed and curved areas cannot be viewed using a narrow view-angle camera, especially in an environment with bad illumination and several obstacles. Theref...

A tire slip fuzzy control solution is designed and implemented in the framework of an Anti-lock Braking System (ABS) comprising a highly nonlinear controlled plant. The fuzzy controllers are designed to work for locally linearized models of the plant. Their parameters are tuned by mapping from simple PI controllers in terms of the modal equivalence principle. The experience from the experiments is incorporated in the design of the rules and the stability analysis enables the controller design. T...

Antilock braking systems are designed to control the wheel slip, such that the braking force is maximized and steerability is maintained during braking. However, the control of antilock braking systems is a challenging problem due to nonlinear braking dynamics and the uncertain and time-varying nature of the parameters. This paper presents an adaptive neural network-based hybrid controller for antilock braking systems. The hybrid controller is based on the well-known feedback linearization, comb...

A stabilizing observer-based control algorithm for an in-wheel-motored vehicle is proposed, which generates direct yaw moment to compensate for the state deviations. The control scheme is based on a fuzzy rule-based body slip angle (beta) observer. In the design strategy of the fuzzy observer, the vehicle dynamics is represented by Takagi-Sugeno-like fuzzy models. Initially, local equivalent vehicle models are built using the linear approximations of vehicle dynamics for low and high lateral acc...

The control of an antilock braking system (ABS) is a difficult problem due to its strongly nonlinear and uncertain characteristics. To overcome this difficulty, the integration of gray-system theory and sliding-mode control is proposed in this paper. This way, the prediction capabilities of the former and the robustness of the latter are combined to regulate optimal wheel slip depending on the vehicle forward velocity. The design approach described is novel, considering that a point, rather than...

This paper presents a new method developed for the optimal design of piezoactive compliant micromechanisms. It is based on a flexible building block method, called FlexIn (flexible innovation), which uses an evolutionary approach, to optimize a truss-like planar structure made of passive and active building blocks, made of piezoelectric material. An electromechanical approach, based on a mixed finite-element formulation, is used to establish the model of the active piezoelectric blocks. From the...

The paper suggests PI controllers for longitudinal slip control in the framework of a laboratory anti-lock braking system (ABS). The new design methods make use of gain-scheduling and iterative feedback tuning. They prove to be relatively simple and transparent thus ensuring low-cost automation solutions. The digital implementation of the controllers is done for the laboratory ABS. Real-time experimental results validate the theoretical approaches.

Friction may well be nature's most useful phenomenon. In machinery in which it is not the driving force, however, friction is an undesirable parasitic phenomenon, generating heat and wasting energy. Large sums are spent each year on lubricants to eliminate as much friction as possible in mechanical devices. On the other hand, when friction is the source of traction and braking, it is important to keep friction at a high level. To achieve this end, much effort and funding are expended on projects...

The purpose of an antilock braking system (ABS) is to prevent wheel lockup under heavy braking conditions on any type of road surface. In this study, multifactor input, dphi/ds and (dphi/ds)/dt, are proposed in the fuzzy controller. This new method not only offers a better braking performance, but also improves the pedal pushing feeling. At last, the design is simulated in Matlab/Simulink environment. And the results indicate multifactor input offer a good braking result and improves the active ...

In this paper, a new type of antilock brake system (ABS) algorithm is developed. A full-time feedback control algorithm differentiates the new ABS from rule-based conventional ABS algorithms. The rear wheels are controlled to create limit cycles around the peak friction slip points. From the cycling patterns of the rear wheels, the optimal slips are defined. The front wheels are controlled to track the optimal slips defined by monitoring the behaviors of the rear wheels. The new algorithm can be...

This paper extends the analysis of empirical methods for describing vehicle–terrain interactions in lunar terrain. Given analytical formulation to predict mobility performance in extraterrestrial environments requires reliable in situ testing campaigns, this imposes fundamental restrictions to conceive a more consolidated theory, and further any possibility to use improved empirical methods to design better space hardware. Hence, we propose an analytical approach to extrapolate data taken in par...

The development of myoelectric-based control systems for prosthetic hands includes several approaches: on-off control, proportional control, direct control, finite state machine control, pattern recognition-based control, posture control, and regression control. All these approaches are considered in the model-based control design framework, which requires accurate models of the human hand. The human hand in such systems is a multi-variable nonlinear dynamical system, with the inputs represented...

Abstract Conventional methods to fabricate intrinsically conductive polymer actuators result in planar morphologies that limit fabricated devices to simplistic linear or bending actuation modes. In this study, we report a conductive polymer formulation and associated 3D printing fabrication method capable of realizing three-dimensional conductive polymer structures that are not subject to such geometric limitations. A light-based 3D printing technique known as digital light processing is employe...

A multi-input, single-output fuzzy logic controller for anti-lock braking system is proposed, where both the slip and the vehicle velocity are considered as the inputs and are regulated equally influencing on the controller decision. The system developed provides both the minimal slip ratio to avoid the wheel blockage and the shortest braking distance of the vehicle thus mitigating the collision with other traffic objects. The comparison of several rule-base blocks are studied aiming to offer th...
