模型跟踪控制应用于非接触感应电能传输

Application of Model Fellow Control on Contactless Inductive Power Transfer

为了将模型跟踪控制应用于非接触感应电能传输系统上,消除广义状态空间平均法对系统矩阵的影响,首先对两者进行原理分析,依据傅里叶变换和拉普拉斯变换的关系及矩阵理论,对状态空间矩阵进行分块和常数化处理,得到适用于模型跟踪控制方法的状态矩阵;通过建立与被控对象输出形式相同的参考模型,分离变量以便单独控制;最后在Simulink平台上对系统进行仿真,验证其可行性.论文提出的将模型跟踪控制应用到非接触感应电能传输系统的方法,使得被控对象可以跟踪参考模型的输出,从而改善电能参数特性,系统建模简单,且可以保存被控对象的物理结构,十分有效.

In order to apply the Model Fellow Control to the Contactless Inductive Power Transfer system, and to eliminate the impact of Generalized State-Space Averaging method on the system matrix, the paper firstly ana- lyzed the two principles above, blocked the State-Space matrixes and converted them into constant-matrix based on the relationship of Fourier transform and the Laplace transform, as well as the matrix theory. Then we got the ap- propriate matrix for the MFCS; through establishing the same output model as the reference model and separating the variables, controlled the output signal individually. Finally, we simulated the system in the SIMULINK platform to verify its feasibility. The approach presented by the paper allows the controlled object to follow the output of the reference model, which can improve the power parameter characteristics. The system modeling is simple and can save the physical structure of the controlled object, and it is very effective.
