摘要为克服单相电压型全桥逆变器系统中不确定性和外界干扰对控制性能的影响,提出了一种新型单相电压型全桥逆变器非线性控制策略。以输出滤波电容电压及其导数为状态变量,建立了逆变器连续数学模型,并进一步得到具有严参数反馈形式的系统非精确数学模型;在此基础上,将反步法和滑模控制相结合,提出了单相电压型全桥逆变器的反步滑模控制策略,可实现系统全局意义下的渐近稳定,有效地克服了反步法对系统模型的依赖性。实验结果表明,当存在不确定参数和外界扰动时,采用所提出的控制方法,系统输出无静差、输出电压谐波含量很少,对直流电压源扰动和负载扰动具有很强的鲁棒性,且同时适用于线性和非线性负载。

Abstract：In order to overcome the impacts of uncertainty and external disturbance on the control performance of the single-phase voltage source full-bridge inverters, a novel non-linear control strategy of single-phase voltage source full-bridge inverter is proposed. The continuous mathematical model of the inverter is established by using the output filter capacitor voltage and its derivative as state variables. And then the strict parameter feedback model considering parameters uncertainty and external disturbance is further developed. Subsequently, combined the backstepping method and sliding mode control, a new backstepping-sliding mode control strategy for the inverter is proposed. The proposed strategy could achieve globally asymptotic stability, and effectively overcome the dependency on the mathematical model of the backstepping method. Experimental results show that, by adopting this novel method, the output voltage has no steady state error and few harmonic contents, also the system is robust to the disturbance of dc voltage source and loads. Furthermore, this control strategy can be applied to both linear and nonlinear loads.

Key words： Single-phase voltage source full-bridge inverter nonlinear control backstepping soliding mode control parameter uncertainty external disturbance
