提出一种基于卡尔曼滤波算法的异步电动机控制方法。根据卡尔曼滤波理论建立观测器,对负载转矩进行实时观测,并利用观测值在系统中形成转矩前馈补偿,极大地提高了系统的动态性能和抗干扰能力。试验证明,该方法简单有效,可以显著提高系统的抗干扰能力和鲁棒性。 An induction motor control method based on Kalman filter algorithm is proposed. According to the Kalman filter theory, the observer is built to observe the load torque in real time. The torque feedforward compensation is formed in the system by using the observed value, which greatly improves the dynamic performance and anti-interference ability of the system. Experiments show that the method is simple and effective, which can significantly improve the anti-interference ability and robustness of the system.
