摘要:
针对脉冲宽度调制器控制降压型直流\|直流（DC\|DC）变换器采用常规的比例积分微分（PID）控制方法存在抖动和延迟等问题，提出一种基于滑模修正PID控制策略的DC\|DC变换器实现方法.在分析滑模控制理论的基础上，利用线性矩阵等式方法来建立DC\|DC转换器的状态空间数学模型，设计滑模PID控制器，构造全局滑模面调整PID控制器输出参数，并用李雅普诺夫函数验证了滑模PID控制器的可靠性.在电感电流连续工作模式下，用不确定性负载的线性平均模型进行了仿真.结果显示：证明所提出的滑模PID控制器不但提高系统对不确定负载的适应性,而且增强了系统在大信号扰动时的鲁棒性，使转换器输出电压有优越的鲁棒性及良好控制性能.
Abstract:
To solve the problem of jitter and delay in a pulse width modulator buck direct current\|direct current（DC\|DC）converter using conventional proportional\|integral\|derivative（PID）control methods, a control strategy based on sliding mode correction PID was proposed. Sliding mode PID controller was designed using linear matrix inequality to construct the global PID sliding surface based on analyses of sliding mode control theory, and its reliability was verified with Lyapunov function. The unified dynamical model of buck DC\|DC converter was set up with nonlinear characteristics and uncertainty load in inductor current continuous. Simulation results show that the controllers improve greatly the dynamic performance of buck DC\|DC converters;the controlled output voltage is robust against load disturbances and the controlled output current of each converter cell is identical.
