The Study on a Novel AC Servo Control System Appling to Self-Propelled Artillery

AC servo control systems based on Field Oriented Control (FOC) have been applied to our self-propelled artillery and other weapons. But the Field Oriented Control (DTC) system has complex structure and more calculations, so the Direct Torque Control method replaces it and becomes a novel AC servo control method for its simple structure and quick response. This paper describes DTC basic principle and establishes a servo system model, finally make a simulation. The simulation results show DTC method is better than FOC method for our self-propelled artillery.
