In trajectory correction technique, speed controling for PM motor is the key. According to the analytical results of electromagnetic torque and mechanical characteristics of PMDC motor, the method of speed controlling for the PM motor by connecting resistors on the armature circuit in series was presented, and a prototype system was established to simulate controlling experiment. Experimental results show that the method of speed control for PM motor's stability is well and fast response. The results provide a reference for speed and attitude determination controlling in the subsequent research of two dimensional trajectory correction fuze.
