摘要
针对无法获得电力逆变器系统精确数学模型问题,提出无模型自适应控制(model-free adaptive control,MFAC)方案。利用动态线性化方法给出电力逆变器系统的紧格式动态线性化数据模型,基于优化技术设计控制算法和伪偏导数估计算法。控制方案的主要特点是只使用电力逆变器控制系统的输入输出数据,不需要电力逆变器的精确数学模型信息。使用MATLAB/Simulink对控制系统性能进行仿真验证,结果表明,电力逆变器控制系统在阻感性负载情况下,所提算法能够实现对期望输出电压的精确跟踪。
In order to solve the problem that the accurate mathematical model of power inverter could not be obtained,a model-free adaptive control(MFAC)scheme for power inverter system was presented.The inverter system was transformed into the compact form dynamic linearization(CFDL)data model by using dynamic linearization method.Then,the control algorithm and pseudo-partial-derivative(PPD)estimation algorithm were designed based on the optimization technique.Instead of the accurate mathematical model,the main feature of this control scheme was that the input and output data of the power inverter control system were only used.The effectiveness of the algorithm was verified in the MATLAB/Simulink environment,the results showed that,under the resistive inductive load,the output of power inverter control system embedded the MFAC scheme could track the desired one accurately.
