Abstract :
This paper deals with the design of an adaptive PID control system for discrete-time SISO non-linear systems. The proposed method is based on the output feedback strictly passive (OFSP) property of the controlled system. A fundamental design scheme of an adaptive PID control system with a parallel feedforward compensator (PFC) introduced in order to realize an OFSP augmented controlled system will be provided.
