针对当前数字控制逆变系统中控制延时和参数扰动等问题，文章将无差拍控制和重复控制相结合，提出一种预测电压控制算法。以单相全桥逆变器为控制对象，设计出预测控制策略并进行系统的MATLAB／SIMU-LINK仿真。仿真结果表明，该预测控制算法有效地改善了系统的暂态和稳态性能，满足一定的控制精度和实时性的要求，具有良好的应用价值。

In order to eliminate the impact of control delay and parameter perturbations in digital control system of inverter, a predictive voltage control method based on the combination of deadbeat control and repetitive con-trol is proposed .The control techniques for single-phase-full-bridge inverter is dealt with in the paper , and it in-troduces the process of predictive control strategy and simulates the system in MATLAB /SIMULINK.It is shown by simulation results that the inverter with this predictive control strategy can achieve a desired steady state and dynamic performance , which meets the requirement of control precision and system real time .Thus, inverters based on predictive control strategy have high application value .
