    • There is provided a digital controller which can reduce a variation in output voltage as compared to the conventional digital controller at the time of abrupt changes in load and in input of a power amplifier. The digital controller is built in the power amplifier for supplying an output voltage vo to a load and is equipped with a manipulated variable calculating unit which detects the output voltage vo to calculate a manipulated variable ξ1 and a signal generating unit which converts the manipulated variable ξ1 into a signal for making the power amplifier operate. A feedforward function from an equivalent disturbance qy caused by the variation in the load is replaced by a feedback function from the output voltage vo and the manipulated variable ξ1, thereby allowing a transfer characteristic from the disturbance qy to the output voltage vo to result in a quadratic differential characteristic. Consequently, the variation in output voltage can be reduced as compared to the conventional controller at the time of the abrupt changes in the load and in the input of the power amplifier.
    • 在负载突然变化和功率放大器的输入时,提供了一种数字控制器,其可以减少输出电压的变化,与传统的数字控制器相比。 数字控制器内置在功率放大器中,用于向负载提供输出电压vo,并且配备有操纵变量计算单元,该操作变量计算单元检测输出电压vo以计算操纵变量xgr1;以及信号产生单元,其将所操纵的 变量&xgr 1转换成用于使功率放大器工作的信号。 由负载变化引起的等效干扰qy的前馈函数由来自输出电压vo和操作变量& xgr1的反馈函数代替,从而允许从干扰qy到输出电压vo的传递特性 具有二次微分特性。 因此,与传统控制器相比,在负载突然变化和功率放大器的输入时,输出电压的变化可以减小。
