| 摘 要： | 采用v分解方法建立了DC-DC变换器的离散时间混杂模型,并将其转换为分段仿射(PWA)形式,把DC-DC变换器的控制问题转化为分段仿射系统的约束优化控制问题。针对带状态和输入约束的离散时间分段仿射系统动态变化快的特点,应用显式模型预测控制方法,并基于多参数二次规划算法得到了关于状态变量的分段线性显式最优控制律,从而进一步得到DC-DC变换器显式模型预测控制系统。数值仿真计算表明:DC-DC变换器的显式模型预测控制是有效的,系统控制的动态性能是优越的。

| Abstract: | A discrete time hybrid model of the DC-DC converter was developed by using the v-resolution modeling approach,and then was transformed into the piecewise affine(PWA) form.Thus,the problem of optimal control of DC-DC converter was cast as the PWA constrained optimal control problem.For the fast dynamic property of discrete-time PWA systems with constraints on inputs and stats,based on multi-parametric quadratic programming method,the explicit model predictive control was applied to the optimal control problem of DC-DC converter,and an explicit piecewise state feedback control law was obtained,and the explicit model predictive control system of DC-DC converter was established.The results of numerical simulations show that the explicit model predictive control of DC-DC converters is effective,and its dynamic properties are satisfying. |
