In this paper, we consider the model reference adaptive control (MRAC) problem of switched linear systems in which the parameters and switching time instants are all unknown. We apply the output feedback variable structure (VS) based adaptive controller to switched linear systems with general relative degrees and show error convergence and signal boundedness properties by multiple Lyapunov functions...
In this paper, we discuss the model reference adaptive control problem of switched linear systems with unknown parameters. Since we do not have information about the system parameters nor the possible abrupt changes of parameters, conventional integral adaptive law do not function well for switched systems. We propose a variable structure based adaptive controller to the switched system and show error...
In this paper, we discuss the model reference adaptive control problem of switched linear systems with unknown switching signals and unknown parameters. We discuss state feedback and output feedback adaptive control for the switched systems. Variable structure based adaptive controllers are applied to the switched systems and error convergence and signal boundedness are shown for a class of switching...
This paper proposes a new type of a non-conventional electro-magnetic actuator (EMA) for a micro-positioner with larger moving range. It is a repulsive magnetic system consisting of a motion carrier and two active coils. The movement of the motion carrier is due to the repelling force between the coils and the magnets affixed to the carrier. First, the dynamic model is derived and analyzed. Next,...
