This paper studies an enhanced passivation method for feedback interconnected switched controllers consisting of N sub-controllers. It is shown that stability and passivity of the closed-loop system are achieved through the feedback interconnection of the passivated switched controller. The passivation technique is established through finding a common gain for the switched controller and therefore...
We consider a feedback switched control system with non-passive subsystems. Introducing a passivation matrix, we transform each non-passive subsystem into a passive one and investigate the passivity of the resulting closed-loop system. The results are further extended to input feedforward passive (IFP) and output feedforward passive (OFP) switched controllers. In addition, we construct a control framework...
We analyze the feedback passivity of a networked control system in which the control packets may be dropped by the communication channel. Specifically, we consider a discrete-time switched nonlinear system with relative degree zero that switches between two modes. At the instants when the communication link transmits the packet successfully, the system evolves in closed-loop and the increase in storage...
