چکیده
To improve the tracking capability and sensorless estimation accuracy of a permanent magnet linear synchronous motor (PMLSM) control system, system based on continuous terminal sliding mode controller (CT-SMC) fuzzy super-twisted observer (F-ST-SMO) was designed. Compared with conventional slide control, CT-SMC can reach equilibrium point in limited time to ensure continuity achieve fast reference speed. Based PMLSM design F-ST-SMO, algorithm is used replace traditional first order algorithm. Meanwhile, rules are introduced adjust gain adaptively, which replaces fixed SMO reduces chattering system. Finally, effectiveness superiority designed proven by simulation experiment.

For the problems of buffeting and phase delay in traditional rotor detection in sensorless vector control of permanent magnet synchronous motor (PMSM), the Sigmoid function is proposed to replace sign function and the approach of piecewise linearization is proposed to compensate phase delay. To the problem that the output of traditional low pass filter contains high-order harmonic, two-stage fi...

متن کاملPosition Sensorless Control of a Permanent Magnet Stepping Motor Based on Sliding Mode Observer
Abstract This paper deals with a position sensorless control of a permanent magnet stepping motor. The proposed controller is designed to reduce the studied actuator oscillations and overshoot which can induce an erratic working. As the mechanical solutions are expensive and cumbersome, the control ones are considered to be the most suitable. Closed loop control of these motors offers significa...
