| Abstract: |
| A strategy of nonsingular terminal sliding mode control is proposed for the voltage regulation system of DSEG （Doubly Salient Electromagnetic Generator）. The structure of DSEG is described and its mathematical model is established，based on which，the operating principle of voltage regulator based on proposed control strategy is analyzed in detail and the corresponding sliding mode surface equation and sliding mode law are given. The control law parameters are calculated according to the constraint conditions of Lyapunov stability equation and the carrier wave intersection with fixed PWM control. A field-circuit co-simulation model is built based on the electromagnetic finite element analysis technique and the control circuit. The results of steady-state and dynamic simulations for DSEG show that，the voltage regulation system of DSEG based on the nonsingular terminal sliding mode control has excellent steady-state and dynamic performances，with small voltage ripple，short recovery time and little dynamic output voltage variation. |
