Ripple Correlation Control (RCC) has been established as a cost function minimization strategy for problems ranging from source impedance matching to static VAR compensators and more recently to electric machinery. The dynamics of machines often makes direct application of RCC not possible or not practical. This paper addresses the fundamental challenges associated with implementation of RCC optimization in electric machinery. Specifically, the paper presents a steady state error analysis of several practical RCC control laws, develops a systematic approach to observer design to cast the optimization of a dynamic process into a static framework, and presents the benefits of an alternative RCC control law for use in electric machinery controllers.
