本文提出了一种采用非线性控制算法的双电压环数字控制结构。提出了一种自适应电压定位（AVP）控制单元，通过产生动态电压基准和动态电流基准实现自适应电压定位。动态参考阶跃调整方法降低了参考更新时钟的高速要求;非线性控制最小化瞬态断言到动作延迟并最大化电感器电流转换速率;以及瞬态检测电路以适应负载电流瞬态的量和转换速率的方式识别负载瞬态。理论、仿真和实验结果证明了该数字控制器的有效性和良好的动态性能。
A dual-voltage-loop digital control architecture with non-linear control algorithm is proposed in this paper. An adaptive voltage positioning (AVP) control unit was generalized to achieve adaptive voltage positioning, by generating dynamic voltage reference and dynamic current reference. A dynamic reference step adjustment method lowers the high speed requirement of reference updating clock; a non-linear control minimizes the transient-assertion-to-action delay and maximizes the inductor current slew rate; and a transient detection circuit recognizes the load transient state in a manner adaptive to the amount and slew rate of load current transient. Theoretical, simulation and experimental results prove the effective operation and excellent dynamic performance of the digital controller.
