三相電壓型PWM整流器的非線性控制研究

摘要：基于非線性系統反饋線性化理論，建立了三相電壓型PWM整流器非線性模型，設計了一種非線性控制器。對三相電壓型PWM整流器非線性控制方法進行了細致的分析與研究，仿真結果表明PWM整流器采用這種非線性控制器比采用普通線性控制器具有更為優越的動靜態性能。 敘詞：整流器；脈寬調制；非線性系統；反饋線性化 Abstract：Base on the feedback linearization theory for nonlinear systems, presenting a nonlinear model for three phase voltage source PWM and designing a nonlinear controller.
