| titleOfInvention | State-limitation-based fuzzy position tracking control method for permanent magnet synchronous motor |
| abstract | The invention discloses a state-limited permanent magnet synchronous motor fuzzy position tracking control method, which aims at the problems of nonlinearity and iron loss in a motor driving and controlling system of an electric automobile, restrains the state quantity and the control quantity of a motor system based on a Barrier Lyapunov function, and constructs a fuzzy self-adaptive position tracking controller by approximating the nonlinear function in the system by using a fuzzy logic system. The method can ensure that the tracking error of the system can be converged to a small enough neighborhood of the origin, and simulation results show that the method ensures that each state quantity of the motor is in a constraint space of the system and the input of the controller is stabilized in a bounded region. The invention realizes quick and effective response to the position tracking control of the permanent magnet synchronous motor of the electric vehicle, and is more suitable for control objects needing quick and dynamic response like an electric vehicle driving system. |
