本文研究了逆变器并联系统在有界意义下的稳定性问题。首先，非线性模型的并联逆变器与一个通用的线性或非线性负载得到通过使用广义耗散哈密顿结构，然后鲁棒下垂控制器，最近在文献中提出的逆变器的并联操作，实施的方式产生一个有界的控制输出。所提出的控制器被称为有界下垂控制器（BDC）。它引入了零增益特性，并能保证闭环系统解的有界性。因此，第一次，闭环稳定性的有界性意义上的并联逆变器的通用非线性/线性负载馈电保证。进一步改进了控制器结构，以提高其对初始条件、数值误差或外部干扰的鲁棒性，同时保持稳定性。此外，调节控制器以避免电压动态中的任何可能的极限环。两个单相逆变器并联运行的非线性负载的实时仿真结果，以验证所提出的BDC的有效性。
In this paper, the stability of parallel-operated inverters in the sense of boundedness is investigated. At first, the non-linear model of parallelled inverters with a generic linear or non-linear load is obtained by using the generalised dissipative Hamiltonian structure and then the robust droop controller, recently proposed in the literature for parallel operation of inverters, is implemented in a way to produce a bounded control output. The proposed controller is called the bounded droop controller (BDC). It introduces a zero-gain property and can guarantee the boundedness of the closed-loop system solution. Therefore, for the first time, the closed-loop stability in the sense of boundedness is guaranteed for parallelled inverters feeding generic non-linear/linear loads. The controller structure is further improved to increase its robustness with respect to initial conditions, numerical errors or external disturbances while maintaining the stability property. Moreover, the controller is tuned to avoid any possible limit cycles in the voltage dynamics. Real-time simulation results for two single-phase inverters operated in parallel loaded with a non-linear load are presented to verify the effectiveness of the proposed BDC.
