| Abstract: | A system with long stroke and large load often has low natural frequency. In some cases its response requests is comparatively high, in especial that the phase lag request is very strict. So a suitable controller should be carefully selected or designed. Here a controller that combines speed and acceleration feedforward with state feedback is presented. The simulation results show that the magnitude and phase performance of the system's frequency response is perfect after that controller is applied. |
