摘　　要：针对永磁同步电机传统滑模观测器存在高频滑模噪声,从而导致精度低、较大抖振以及相位延迟的问题,以及使用固定的滑模参数会使估算精度受到参数干扰而产生误差的情况,造成控制精度比较低,提出一种改进的粒子群优化(IPSO)算法超螺旋滑模观测器作为无位置传感器控制的改进方法。该方法首先进行永磁同步电机数学模型的建立,然后建立超螺旋滑模观测器,最后应用改进粒子群算法。超螺旋算法采用积分形式来消除高频噪声,减小误差抖振以及相位延迟。引入改进粒子群算法对滑模观测器参数进行滑模参数寻优,通过在线调整滑模系数可以获得较高的收敛速度和稳态精度。仿真和实验结果验证了该控制策略能有效抑制系统抖振,减小相位延迟,且估计精度高,进一步说明该策略在电动汽车中有一定的可行性。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.
