| Abstract: | In order to improve the swift dynamic characteristics of permanent magnet synchronous motor (PMSM) and restrain influence on servo system performance owing to uncertain factors of parameter diversification and load disturbance,a novel fuzzy switch algorithm based on smooth switch is proposed and a new fuzzy PID compound controller was designed,which is adopted in the PMSM servo system.The simulative and experimental results show that the controller has advantages of both fuzzy controller and PID controller,... |
