Abstract Nondeterministic finite transition systems (NFTSs) have been widely used in the past decade to (approximately) abstract physical systems described by ordinary differential equations. One can leverage the NFTSs and algorithmic machinery for automated synthesis of finite systems to automatically synthesize controllers for the original physical systems against complex logical specifications. The current state detection/estimation of NFTSs is of fundamental importance, as the current state ...

The paper presents modeling, control and analysis of an urban public transport network. First, a centralized system description is given, built up from the dynamics of individual buses and bus stops. Aiming to minimize three conflicting goals (equidistant headways, timetable adherence, and minimizing passenger waiting times), a reference tracking model predictive controller formulated based on the piecewise-affine system model. The closed-loop system is analyzed with three methods. Numerical sim...

The paper considers constrained linear systems with stochastic additive disturbances and noisy measurements transmitted over a lossy communication channel. We propose a model predictive control (MPC) law that minimizes a discounted cost subject to a discounted expectation constraint. Sensor data is assumed to be lost with known probability, and data losses are accounted for by expressing the predicted control policy as an affine function of future observations, which results in a convex optimal ...

Abstract Metabolic engineering has enabled the production of a wealth of chemicals with microorganisms. Classic strategies for pathway engineering rely on the expression of heterologous enzymes in a host that convert native intermediates into target products. Although traditional implementations are based on open-loop control, recent advances in gene circuit engineering offer opportunities for building feedback systems that dynamically control pathway activity. Here we present a framework for th...

We study the dynamic consequences of lost sales when there is insufficient inventory to satisfy demand. Demand is assumed to be independently and identically distributed and drawn from a normal distribution. We consider the industrially popular order-up-to policy with unit lead time is used to make replenishment orders. In this scenario, we obtain expressions for the order and inventory distributions, allowing us to quantify the Bullwhip and Net Stock Amplification ratios. We show that both thes...

Abstract This paper addresses the filtered-error recursive least squares (FeRLS) algorithm for disturbance feedforward control in active vibration isolation systems. The controller structure consists of a generalized finite-impulse response (FIR) filter to include a set of pre-determined poles and self-tuning zeros. In addition, residual noise shaping is included to add frequency weighting and improve robustness. Compared to existing filtered-error least mean squares (FeLMS) algorithms, two majo...

Abstract In this paper, we propose an approach for parametric system identification for a class of continuous-time Lur’e-type systems using only steady-state input and output data. Employing a quasi-Newton optimization scheme, we minimize an output error criterion constrained to the set of convergent models, which enforces a stability certificate on the identified model. To compute the steady-state model response efficiently, we adopt the Mixed-Time-Frequency (MTF) algorithm. Furthermore, using ...

Abstract In this article a comparison of two controllers for the active suppression of flutter of a flexible remotely-piloted aerial vehicle is presented. The H∞ technique is used for both, but the first relies on the standard (non-structured) approach and the second on the structured synthesis. High-fidelity models derived from finite element modeling are used to verify the performance of the obtained controllers. Reduced-order models are used for the control synthesis, which are obtained from ...
