【Abstract】 A cascaded control of master-slave circuit was put forward aimed at requirement of high speed and high precision in an AC servo system,based on DSP control chip of 28X series.PI controller of velocity loop was introduced to reduce system steady-state error and to increase system response speed,and second order feedforward proportional control of position loop was designed to improve the system dynamic tracking accuracy.Parameters of the master-slave circuit controller were identified by experimental research at different conditions.The results show that the proposed cascaded controller can guarantee the dynamic performance of servo system.更多还原
