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(tǒng)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(shè)計(jì)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(jìn)行了細(xì)致的分析與研究，仿真結(jié)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(yōu)越的動(dòng)靜態(tài)性能。 敘詞：整流器；脈寬調(diào)制；非線性系統(tǒng)；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.
