Abstract:
In a direct transmission gun control system based on turret seat ring motor,the SVPWM modu-lation dead time causes the fluctuation of current and torque,which affects the low-speed stability. Aiming at the problems above,the design and the control model of turret seat ring motor were analyzed firstly. And then,the principle of dead time in single-phase bridge inverter,the effects of dead time in voltage vector space and its relationship with direction of three-phase current were discussed. On the basis of that,the e-quivalent voltage disturbance of dead time was built up and the compensation control method based on ac-tive disturbance rejection control technique was proposed. The simulation and test result shows that the in-fluences caused by the dead time were restrained and the fluctuation of current and torque were reduced soundly. And the method is simple and prone to realize in engineering.
