Control of a high-speed switched reluctance machine using only the DC-link measurements

By S Sava Marinkov and AG Bram de Jager


\u3cp\u3eIn this paper we present a novel speed control strategy for a high-speed Switched Reluctance Machine that uses only the DC-link voltage and current measurements. This eliminates a number of hardware components such as position, speed, phase current and phase voltage sensors. It further lowers the machine manufacturing costs and increases the system's reliability. The design incorporates a nonlinear observer based on the DC-link current error. The proposed speed and position estimation method shows stable and fast convergence properties, which is also observed in closed-loop simulations.\u3c/p\u3
