Asynchronous motor instruction filtering discrete control method based on observer

The invention belongs to the technical field of asynchronous motor position tracking control, and particularly discloses an asynchronous motor instruction filtering discrete control method based on an observer. According to the asynchronous motor instruction filtering discrete control method, an asynchronous motor discrete system model is established in combination with an Euler method for the problem of easy input saturation of an asynchronous motor; constructing a dimension reduction observer to estimate the rotor position and angular velocity of the asynchronous motor; an instruction filtering control technology is introduced into a traditional backstepping method, and the problems of calculation complexity and causal contradiction existing in a backstepping control algorithm are solved. A high-order nonlinear term in an asynchronous motor discrete system is processed by using an RBF neural network, and an asynchronous motor instruction filtering discrete controller based on the observer is constructed.
