| Abstract: | Linear feed system driven by linear motor is widely used in CNC machine tools,but its dynamic performance is impacted by its strong coupling and nonlinearity.In order to meet the performance requirements of high speed and high precision in machining,an optimization method is proposed for PID parameters of servo system based on kernel partial least squares(KPLS)and bat algorithm(BA),which avoids the inefficiency of off-line simulation.With the establishment of regression model between rise time,maximum velocity overshoot and PID parameters,BA is applied to identify the optimal combination of parameters.Experimental results indicate that the method can effectively optimize the PID parameters,and significantly shorten the rise time under a constraint of certain maximum overshoot,to improve the dynamic performance of the linear feed system. |
