摘　　要：数字化控制是当前变换器控制技术的主流发展方向。由于比例积分微分(PID)闭环控制计算复杂度高,文中引入简单的逻辑判断数字变量来替换传统的PID闭环控制的控制策略,提出一套完整且简单有效的变换器数字化控制方案并给出了具体的实施方法,解决通用数字信号处理器(DSP)实现电源的全数字控制,简化了数字控制的算法,节省了资源,降低了当前广泛应用的数字化控制策略对于专用DSP的依赖。Digital control is the main development direction of the power converter control currently.Due to the high computational complexity of proportion integration differentiation(PID)closed-loop control,the simple logical digital variable is introduced to re-place the traditional PID control strategy of the PID closed-loop control.A set of compete,simple and effective digital convertercontrol scheme and detailed implementation method are put forward.The scheme solves the all-digital control problem of the general digital signal processor(DSP).It makes the digital control algorithm simple,saves the resources and reduces the dependence ofthe dedicated DSP for the digital control used widely.
