中文摘要：
设计了一种具有PI-D结构的HVDC定电流控制器并提出了相应的控制器参数整定方法,在避免了控制器参数整定盲目性的同时提高了其控制性能。在传统PI控制器的反馈通路上增加了具有提高阻尼作用的微分环节,通过推导包含控制器参数的直流系统传递函数表达式绘制出控制参数变化时系统Bode图的变化规律,根据上述规律和系统的时域响应要求对控制器参数进行整定。通过上述方法设计了CIGRE HVDC标准模型整流侧的PI-D定电流控制器,同时设计了传统的PI和PID控制器进行比较。仿真实验表明,相对于传统PI和PID控制系统,采用PI-D控制器的直流系统具有更好的时域响应特性和抗干扰能力。
英文摘要：
A type of constant current control system which is devised with PI-D structure is designed in this paper, and the parameters optimization method is also put forward. First, a differentiator is added to the feedback path of the traditional PI controller, thus constituting a controller with PI-D structure. Then, for-mulate the transfer function expression which contains the controller parameters of the HVDC system, and draw the Bode diagrams of the system as the control parameters vary. According to the variation of the Bode diagram, the most appropriate parameters can be found. According to the above-mentioned method, a constant current controller with PI-D structure is designed for the CIGRE HVDC benchmark model. To validate the performance of the designed controller, a traditional PI-D controller is also designed as the contrast. The simulation test demonstrates that, compared with the traditional PI and PID controller, the PI-D con- troller has better time-domain response characteristic and anti-interference ability.
