Abstract: In allusion to the problem of high frequency sliding mode noise in traditional sliding mode observers for permanent magnet synchronous motors (PMSM), which leads to low accuracy, large chattering, and phase delay. The use of fixed sliding mode parameters can cause estimation accuracy to be affected by parameter interference, resulting in relatively low control accuracy. An improved particle swarm optimization (IPSO) algorithm super spiral sliding mode observer is proposed as an improved method for sensorless control. The mathematical model of PMSM is established by means of this method, then a super spiral sliding mode observer is built, and finally the IPSO algorithm is applied. The hyper spiral algorithm can use integral form to eliminate high?frequency noise, reduce error jitter and phase delay. An IPSO algorithm is used to optimize the sliding mode observer parameters, higher convergence speed and steady?state accuracy can be achieved by adjusting the sliding mode coefficients online. The simulation and experimental results show that this control strategy effectively can suppress system chattering, reduce phase delay, and has high estimation accuracy, further demonstrating the feasibility of this strategy in electric vehicles.
