一种新的逆变器控制算法的设计

提出一种基于回归支持向量机的逆变器控制算法,该控制算法由常规反馈控制和函数逼近器两部分组成,利用优化控制理论来设计常规反馈控制器,并采用回归支持向量机作为函数逼近器来建模逆变器的逆动态,仿真实验显示:所设计的控制策略具有较好的抗干扰能力,对不同的负载均有较好的输出响应,并对负载突变有较强的鲁棒性.

Design of a new kind of control algorithm for inverter

This paper proposes a control algorithm for inverter based on support vector machine,which consists of conventional feedback control and function approximator. In this control algorithm,the optimal control theory is used to design the conventional control algorithm,and regression support vector machine is used as a function approximator to simulate the inverse dynamic state of inverter. Simulation results show that the designed control strategy can effectively improve the anti-disturbance capability of inverter system. The proposed scheme has excellent output response for different loads,and is insensitive to load variations.
