Adaptive generalized PID controllers and fuzzy logic coordinator for load sharing in SMSE

This paper describes the control of the energy transfers in Systems of Multiple Sources of Energy (SMSE). The considered SMSE is a Linear Time Varying (LTV) system in view of the sources and load fluctuations. The proposed adaptive generalized PID controllers regulate the DC bus voltage and the currents provided by each source whatever the sources and load fluctuations. These local controllers cooperate with a fuzzy logic coordinator that tunes the power ratio provided by each source according to the load and duty cycle estimations.
