The paper considers the problem of parameter identification of the surface mounted permanent magnet synchronous motor (SPMSM) with pulse width modulated (PWM) inverter in the presence of dead time of power switches and other nonlinear distortions. Parameter identification of the SPMSM is required for the tuning of the torque control loop, because in some cases, the exact values of phase resistances and inductances are not known. In the absence of nonlinear disturbances, the problem of SPMSM para...

In this paper, we consider effects of impurity diffusion and convection in strained elastic materials with the help of a two-component continual model, that takes into account change in the rigid properties of the material. Two new kinds of solutions, which describe propagation of localized waves, have been found. The first type of solutions describe waves which look like sharply localized peaks (solitary waves). When these type of waves propagate, they change their forms and, as a result, a for...
