摘　　要：比例谐振控制在逆变系统的控制中具有较强的跟踪正弦指令能力,但物理实现时存在采样信号通过调理电路所带来相位延迟和比例谐振控制算法离散化及控制参数优化的问题。针对上述问题,讨论了一种数字相位补偿算法,并对准比例谐振控制算法的数字化实现进行理论推导,使用双线性变换法对该算法进行离散化处理,给出了控制参数选取公式以及微处理器实现方法。通过Simulink仿真验证该实现方法的可行性,以DSP为控制器,构建实验平台,实验结果表明该控制方法可有效消减系统输出的总谐波畸变,具有良好的跟踪能力。Proportional resonance control has a strong ability to track sinusoidal instructions in inverter system,but there are some problems in the physical implementation,such as phase delay caused by sampling signal through the conditioning circuit,discretization of proportional resonance control algorithm and optimization of control parameters.To solve these problems,a digital phase compensation algorithm is discussed in this paper,and the digital realization of the proportional resonance control algorithm is theoretically derived,the algorithm is discretized by bilinear transformation method,and the control parameter selection formula and the microprocessor implementation method are given.The feasibility of the proposed method is verified by Simulink simulation,and the experimental platform is built with DSP as the controller.The experimental results show that the proposed control method can effectively reduce the total harmonic distortion of the system output and has good tracking ability.
