Speed Control of PM Linear Synchronous Motor Based on Disturbance Observer and Single Neuron PID controller
In permanent magnet linear synchronous motor (PMLSM) direct drive system,disturbance caused by load disturbance and perturbation of motor parameters would reduce the control precision in a certain extent.In order to restrict the disturbance in PMLSM direct drive system,a vector control (VC) strategy based on the disturbance observer (DOB) was proposed in this investigation.By using the observed disturbance of DOB to adjust the given value of current in speed loop,the compensation for a sudden disturbance is optimized and a high precision of PMLSM drive system is obtained.For the sake of improving the dynamic performance under unknown disturbances,the traditional PID controller in speed loop was replaced by a single neuron PID controller,which leads to a good adaptive capability and a better starting performance in a given speed.Finally,a higher steady precision and robustness would be realized.
