This paper presents the design of an output feedback stabilization controller for nonholonomic control systems with strongly nonlinear uncertainties and unknown time delays. By constructing a novel Lyapunov functional, the uncertainties of unknown time delays are compensated for. Based on the proposed observer, state scaling technique and backstepping recursive approach are applied to design a nonlinear...
This paper presents a control strategy for stabilization of the nonholonomic control systems with strongly nonlinear uncertainties and unknown time delays. By constructing appropriate Lyapunov functional, the uncertainties of unknown time delays are compensated for. State scaling technique and backstepping recursive approach are applied to design the robust nonlinear state feedback switching controllers,...
This paper presents a method of optimizing number of turns of the main and radial force winding for a bearingless switched reluctance motor (BSRM) with 12/8 teeth configuration based on its mathematical model. The radial force and torque of BSRM are analyzed on condition of different combinations of the magnetomotive force of two kinds of windings. The winding configuration has a strongly influence...
In this paper, two kinds of control strategies applied to a switched reluctance motor (SRM) with 12/8 teeth configuration have been analyzed based on a three-phase bridge converter. The first strategy is that the three phase SRM windings have to be connected in delta, with a separate diode connected in series with each phase, which is possible to control the voltage and current of each phase independently...
