speed controller
3.A novel hybrid speed controller based on conventional PID controller and neural network direct inverse controller is presented.
5.One of the fuzzy controllers functions as speed controller, while the other two function as magnetic thrust controller and magnetic flux controller respectively.
7.Three factors of influencing rotation speed fluctuation, torque, feedback of rotation speed and plus of speed controller, were analyzed. Resolvents in allusion to each factors were given.
8.In order to realize high accuracy of real-time control of speed and torque, a kind of DTC speed controller based on sliding mode variable structure is designed.
9.The simulation results show the fuzzy adaptive speed controller has more high performance than the traditional indirect model reference adaptive controller and the track of parameters is also fast and exactness.
