| Abstract |
In machine tool applications the high dynamic performance of synchronous servo drives will cause undesired oscillations of the mechanical parts of the load. To avoid these oscillations, a state variable controller was implemented on a signalprocessor system. The necessary state variables as well as the load torque were reconstructed by an observer by means of the motor speed only. The tuning of the controller and the observer is done automatically by the signalprocessor. A special identification method based on a FFT algorithm is suggested to build up the model of the plant, which is necessary for the state observer. The procedures were proved by experimental tests with a machine tool. |
