Abstract
A previously reported (Campos-Canton and Espinosa-Perez, 1999) control law that solves the output voltage control problem for a single-phase voltage-source UPS inverter is experimentally evaluated. The adaptive nonlinear controller was developed considering a half-bridge DC-AC power converter connected to a (linear) resistance load. The evaluation procedure considers the following topics: verification of the stability and convergence theoretical properties, evaluation of the dynamic practical response, disturbance (load change) rejection capability, behavior under low size (and then cost) passive elements and (relative) low switching frequency. It is shown that the controller under study satisfies in a remarkable way all the above evaluation criteria.
先前报道的(Campos-Canton and Espinosa-Perez, 1999)控制律解决了单相电压源UPS逆变器的输出电压控制问题，并进行了实验评估。针对连接线性电阻负载的半桥直流-交流功率变换器，设计了自适应非线性控制器。评估程序考虑以下主题:稳定性和收敛性理论特性的验证，动态实际响应的评估，干扰(负载变化)抑制能力，小尺寸(然后是成本)无源元件和(相对)低开关频率下的行为。结果表明，所研究的控制器较好地满足上述评价标准。
