摘要:逆变器在各领域有着广泛应用，但由于大量非线性负载的存在以及参数的时变性，当系统发生扰动时，传统PID控制方法已经难以达到控制要求。近年来提出的将传统PID与重复控制或模糊控制相结合的综合控制方法也存在动态响应较差的缺点。本文以单相全桥逆变器为例，为了改善输出电压波形和电能质量，提出一种基于GM（0,N）模型的灰色PID控制方法。 将灰色控制与PID控制相结合，通过灰色估计量对干扰提前补偿，在保证逆变器良好动态性能的基础上，达到抑制系统扰动和提高输出电能质量的目的。用MATLAB进行仿真，结果表明，该控制方法具有良好的动态响应性能，能够有效抑制外界扰动，输出高质量电压波形，具有较强的鲁棒性和环境适应能力。

Abstract:The inverter is widely used in various fields，but due to the existence of a large number of nonlinear loads and time-varying parameters，the traditional PID control method is difficult to achieve the requirements when the system is disturbed. In recent years，the integrated control method of combining traditional PID with repetitive control or fuzzy control has the disadvantage of poor dynamic response. In order to improve the output voltage waveform and power quality， taken the single-phase full-bridge inverter as an example，a grey PID control method based on GM（0，N） model was proposed. The idea of combining grey control and PID control was adopted， by using the grey estimator to compensate the disturbance in advance，the purposes of restraining system disturbance and improving the power quality could be achieved on the basis of guaranteeing good dynamic performance of the inverter. The simulation results in MATLAB environment showed that the proposed control method was in good dynamic response performance and it could suppress external disturbances effectively and output high quality voltage waveform，meanwhile，it was endowed with strong robustness and environmental adaptability.
