摘　　要：研究非线性系统的控制问题具有重要的理论意义和实用价值。高压直流输电系统(简称HVDC系统)是典型非线性系统,HVDC系统是高度可控的,其中控制系统是直流输电技术的核心。HVDC系统能否正常运行与其基本控制器的性能息息相关。论文对鲁棒近似反馈线性化控制方法进行了研究,研究结果解决了一类非线性系统的控制问题,同时应用到HVDC系统中,并设计了相应的控制器。It is valuable in both theoretical and practical area to study the control of nonlinear systems. High Voltage Direct Current Transmission （HVDC） is a typical nonlinear system. HVDC is high controllable. The control system is the core of DC transmission system. The performance of its basic controller decides the operation condition of HVDC system. This paper researches and improves a novel nonlinear robust approximate feedback linearization method based on model observers to solve the control problems for a class of nonlinear systems. Also the application problems of HVDC control system are discussed in detail. And a nonlinear controller for HVDC system is designed.
