摘　　要：针对新能源发电的间歇性和不确定性导致电力弹簧(ES)系统模型参数变化及控制性能降低的问题,本文提出一种应用于ES系统的无模型自适应控制(MFAC)策略,仅使用ES的输入输出数据实时更新控制律方程和伪偏导数估计方程,通过紧格式动态线性化算法将ES的输入输出数据描述为紧格式线性化数据模型来替代ES的非线性系统,从而实现ES的无模型自适应控制。通过Matlab/Simulink仿真模拟ES系统的电压稳定效果。结果表明,与传统的比例积分(PI)控制相比,电压稳定响应速度提升了0.07s,电压波形畸变率降低了6.43个百分点,验证了本文所提控制策略的优越性。In response to the intermittency and uncertainty of renewable energy generation,which leads to changes in the model parameters of the electric spring(ES)system and a decrease in control performance,this paper proposes a model-free adaptive control(MFAC)strategy applied to the ES system.This strategy involves updating the control law equation and pseudo-derivative estimation equation in real-time using only the input-output data of ES.Through the compact form dynamic linearization algorithm,the input-output data of ES is described as a compact form dynamic linearization data model to replace the non-linear system of ES,thus achieving model-free adaptive control of ES.To verify the superiority of the control strategy proposed in this paper,the voltage stabilisation effect of the ES system is simulated by Matlab/Simulink.The results show that the voltage stabilisation response speed is improved by 0.07s,and the voltage waveform distortion rate is reduced by 6.43%,compared with the traditional proportional integral(PI)control strategy.
