| Abstract: | A variable speed drive system with v.s. motor suitable for impulse load and based on the phase-locked loop (PLL) technique is proposed. This system has two distinguishing features, namely, a specially-designed motor with separate excitation windings for drivings and braking modes to improve the motor dynamic performance and a specially-designed PLL control scheme to improve the anti-interference performance, in which a separate frequency detector, phase detector channels and a speed comparator are used. Experimental results concerning a fuel pump testbed show that the system performance is excellent. |
