Abstract

This paper presents the design and implementation of an adaptive PID control system for a high
performance Switched Reluctance Motor (SRM) drive. The concept behind the proposed control system is
to use an adaptive PID controller in steady state as well as transient state, which implements the control excellently in most cases. The modality of the control for the adaptive PID controller is such that the coefficients
of the controller are adaptable during the running conditions. Thus, the PID controller along with adaptable
coefficients is implemented to take the advantage of its positive attributes. The adaptive PID controller for
SRM drive is implemented through a TMS320F2812 DSP to evaluate the performance. The implementation
is based on discrete time PID controller, whose coefficients are derived from practical experiments at
different operating conditions with disturbances. Experimental results have shown excellent tracking
performance of the proposed control system, and have convincingly demonstrated the usefulness of the
adaptive PID controller in high performance SRM drives with uncertainties.
