Abstract：Aiming at a piezoelectric servo tool holder system’s inherent low sensitivity and a series of vibration problems in process,a new piezoelectric servo tool holder displacement output control technique was proposed by using the neural network optimization algorithm. Here,the system transfer function was firstly obtained,then internal relations were explored,and finally the PID closed loop step response curve was outputted. By means of a PID controller,the closed-loop control of the system was realized using the BP neural network algorithm. Test results showed that after the tool holder platform is controlled with a traditional PID controller,its output displacement error is reduced,the average error is 0.174 3 μm,and the response time to reach the steady state value is 0.36 s; using the BP neural network combined with PID control technique,the average error can be reduced to 0.112 6 μm,the response time decreases greatly to reach 0.15 s, compared with the traditional control technique,the control performances,such as,response speed and overshoot are significantly improved,at the same time,the reliability of this control process is comprehensively considered.
