ABSTRACT
To solve the problem of low speed servo tracking accuracy of micro-texture machine tools, based on the electromechanical coupling dynamic model, a control scheme combining improved seeker optimization algorithm (ISOA) and feedforward compensation PID is proposed, and the control structure of ISOA+ feedforward PID controller is designed, and the PID parameter optimization design is completed. In order to verify the actual effect of the control strategy, a simulation experiment platform is built by Matlab, and compared with the traditional intelligent optimization algorithm. The simulation results show that the feedforward compensation PID based on ISOA optimization has better optimization effect and greatly improves the speed tracking performance, which verifies its correctness and effectiveness.
