当逆变器为公共负载供电时，要求根据其额定功率分担负载。在本文中，鲁棒下垂控制器（RDC）在文献中提出的实现精确的比例功率分配的PWM逆变器的方式来实现，以确保有界的闭环性能。使用非线性李雅普诺夫方法，它示出的控制器结构允许控制输入保持在一个预定义的范围内。在保持RDC的主要理论的同时，所提出的有界下垂控制器（BDC）被证明可以保证闭环系统在广义耗散Hamilton形式给出的一般负载情况下的有界性意义上的稳定性，该形式可以描述线性和非线性负载动态。给出了两个并联运行的单相逆变器的扩展仿真结果，以验证BDC对于线性和非线性负载情况的有效性。
When paralleled inverters feed a common load, it is required that the load is shared according to their power ratings. In this paper, the robust droop controller (RDC) proposed in the literature for achieving accurate proportional power sharing for paralleled inverters is implemented in a way to ensure a bounded closed-loop performance. Using non-linear Lyapunov methods, it is shown that the controller structure permits the control input to stay within a predefined range. While maintaining the main theory of the RDC, the proposed bounded droop controller (BDC) is proven to guarantee the stability of the closed-loop system in the sense of boundedness for the general load case given in the generalized dissipative Hamiltonian form, which can describe both linear and non-linear load dynamics. Extended simulation results for two single-phase inverters operated in parallel are presented to verify the effectiveness of the BDC for both a linear and a non-linear load case scenario.
