| Abstract: | This paper introduces the chopping control scheme of the switched Reluctance (SR) drive at low speed and its single-pulse control scheme ac high speed. The optimal range of motor parameters and the effects on the efficiency and torque due to their variations are described. On the basis of analyzing the Fuzzy control, the PI control and the feature of the system itself, a Fuzzy PI control algorithm has been presented according to the above control schemes. The implementation of the algorithm on the SR drive is also discussed in detail. The conflict between the dynamic-state and the steady-state performances has been solved effectively by the technology of coarse and fine adjustment. At the end of this paper, experimental results obtained from a 5.5kW SR132-8/6 prototype are given. Tests show that the control method is excellent. |
