【摘要】：感应耦合电能传输系统通过非接触的方式将系统能量从电源侧传递至负载侧。由于该系统具有负载参数变化、系统结构复杂、工作频率高等特点,系统控制器面临着设计难的问题。提出了一种基于滑模控制理论的输出电压控制器,采用移相控制方法实现了对输出电压的控制。该控制方法有效降低了系统建模难度,同时提高了系统输出电压响应特性。通过简化系统结构,推导出滑模控制器的具体表达式,并给出了滑模控制系数的选取方法。通过建立IPT实验系统,在不同负载工作工况条件下进行实验验证。对比传统PI控制方法和所提出的滑模控制方法,实验结果表明滑模控制方法响应更快、对系统负载参数变化不敏感、鲁棒性及动态性能更好,能够较好控制IPT系统的输出电压。
[Abstract]:Inductively coupled power transmission systems transfer system energy from the power side to the load side in a non-contact manner. Because the system has the characteristics of variable load parameters, complex system structure and high working frequency, the system controller is faced with the problem of difficult design. An output voltage controller based on sliding mode control theory is proposed in this paper. The phase shift control method is used to control the output voltage. The control method can effectively reduce the difficulty of system modeling and improve the system output voltage response characteristics. By simplifying the structure of the system, the concrete expression of the sliding mode controller is derived, and the selection method of the sliding mode control coefficient is given. Through the establishment of IPT experimental system, the experimental verification is carried out under different load working conditions. Compared with the traditional Pi control method and the proposed sliding mode control method, the experimental results show that the sliding mode control method can control the output voltage of the IPT system better than the traditional Pi control method and the sliding mode control method, which is not sensitive to the change of system load parameters, and has better robustness and dynamic performance.
