Abstract: According the problem that brushless DC motor(BLDCM) control system is to load disturbance and parameter perturbation, this paper designed a robust controller based on the H∞ control, which settled the conflicts that existed between the tracing performance and anti-jamming capability in traditional controller. Simulation results show the controller has robustness in tracing without steady state error.
