A controlling strategy of limited angle brushless torque motor（LABLTM） was designed through simulating and optimizing. The double-closed loop（position loop and current loop） controller scheme, the threeclosed loop（position loop, angular speed loop and current loop） controller scheme and the four-closed loop（position loop, angular acceleration loop, angular speed loop and current loop） controller scheme were proposed, and they were simulated and analyzed on model ZD30 LABLTM. The results show that the four-closed loop controller scheme is the optimal controlling strategy. The prototype of the LABLTM and its driving module were tested on an engine and its speed regulation performance was measured. The results show that the designed controlling strategy has a better performance and the experimental result is in agreement with the simulated result, and it can meet the requirement of the electronic governor actuator of diesel engine.
