Abstract

This article deals with the trajectory tracking problem for the angular velocity of a DC-motor shaft using a buck-boost-converter as the switch regulated electronic drive. The main result of our proposed control scheme is that a linear time-varying controller results from the consideration of the exact tracking error dynamics and static passive output feedback controller design. The measuring of the angular velocity is not really necessary and the control law is synthesized using only a linear time-varying combination of the converter current and voltage variables. The voltage reference trajectory for the converter is generated exploiting a partial differential flatness property of the combined system. The reference trajectories of the average control and the input current are calculated via stored energy considerations and planning for the initial and final stationary regimes. The discrete switching control realization of the designed continuous feedback control law is accomplished by means of a traditional PWM-modulation scheme. Experimental results are provided

buck - boost变换器驱动的直流电机精确跟踪误差动态无源输出反馈控制器

本文研究了采用升压变换器作为开关调节电子驱动的直流电机轴角速度轨迹跟踪问题。我们提出的控制方案的主要结果是线性时变控制器的结果是考虑了精确的跟踪误差动态和静态无源输出反馈控制器的设计。角速度的测量实际上是不必要的，并且控制律仅使用变换器电流和电压变量的线性时变组合来合成。利用组合系统的偏微分平坦性，生成了变换器的电压参考轨迹。平均控制和输入电流的参考轨迹是通过存储能量的考虑和初始和最终平稳状态的规划来计算的。所设计的连续反馈控制律通过传统的pwm调制方案实现了离散开关控制。给出了实验结果。
