| 摘要: |
| 分析了内模控制（IMC）理论的优越性，推导了HVDC控制系统的传递函数，在IMC理论基础上设计了直流控制系统IMC-PID控制器。控制系统的性能指标采用平方积分误差值（ISE）衡量，鲁棒稳定性指标采用M值进行评定，在综合考虑两者的基础上进行IMC-PID控制器参数的整定。在MATLAB中搭建标准模型进行数字仿真，结果显示在系统参数发生一定变化时系统仍能够保持稳定，具有较好的动态性能，由此证明了所提设计方法的可行性和有效性。 |

| Abstract: |
| The superiority of IMC（Internal Model Control） is analyzed and the transfer function of HVDC control system is deduced. An IMC-PID controller based on IMC theory is designed for HVDC control system. Its performance is evaluated by ISE（Integral of Square values of Errors） and its robustness is deduced by M values，both of which are applied in the parameter setting for IMC-PID controller. The benchmark model is built with MATLAB for digital simulation and the simulative results illustrate that the system has excellent dynamic performance and keeps stable when system parameters change within a certain range，which proves the feasibility and effectiveness of the proposed design method. |
