摘要
在PWM DC/DC变换器中,为了提高系统的目标值跟踪特性和干扰抑制特性,通常采用PID调节器.由于这种方式为单自由度控制,所以它的目标值跟踪特性最佳和干扰抑制特性最佳不可兼得.提出了2-DOF PID控制的PWM DC/DC变换器控制模型,并进行了仿真.结果表明了方案的正确性.
To improve the system＇s command tracking and disturbance rejection of the PWM DC/DC converter, the PID regulator is usually used. But the routine method can only make a compromise of the excellent command tracking and disturbance rejection due to its single-freedom regulator control. A new simulation model ofPWM DC/ DC converter based on double-freedom PID regulator was proposed. The results of simulation show that the proposed method has very good dynamic response performance of both the command tracking and disturbance rejection.
