Comparative Study of Voltage Control for Linear Switched Reluctance Generator for Wave Generation System

摘要

In order to study the stability of the output voltage of the linear switched reluctance generation (LSRG) for wave power system, three kinds of controllers are applied to track the output voltage of the system in this paper. The hardware structure and operation of the LSRG control system are introduced. The LSRG voltage control system is developed by the dSPACE control platform. The proportion integral differential (PID) controller, fuzzy PID controller and sliding mode controller are introduced in this article to conduct multiple experiments. The experimental results show that the voltage precision of the power generation system is relatively high under the fuzzy PID control scheme and an absolute error of ±0.2 v can be achieved.
