一种新型高性能控制器的研究与应用

鉴于在控制实际中存在的不确定性问题, 提出了一种针对大滞后过程的不确定性抑制的新型高性能控制器(New higher performance controller, NHPC).基于在新型观测方法和新型控制方法包括新型滤波方法上的良好进展, 将一种新型超前观测器(New advanced observer, NAO)、一种内反馈控制器(Internal feedback controller, IFC)包括一种正弦跟踪滤波器(Sinusoid tracking filter, STF)等用于构造NHPC.将NHPC运用于大滞后过程控制, 能够对较宽的范围内的时变性和非线性等不确定性问题进行较好的抑制.数学分析、仿真实验和实际电力控制工程应用的结果验证了本文所提观点和方法的正确性和有效性.

Research and Application of a New Higher Performance Controller

As the uncertainty in automatic control, a new higher performance controller (NHPC) of uncertainty suppression for large-lag process is proposed. Based on good progress in new observation methods and new control methods as well as new filtering methods, a new advanced observer (NAO) and a internal feedback controller (IFC) as well as a sinusoidal tracking filter (STF), etc. are used to construct NHPC. NHPC which can effectively suppress the time variability and nonlinear uncertainty in a wider range is used to large-lag process control. The mathematical analysis, simulation experiments and actual power engineering application results verify the correctness and effectiveness of the proposed ideas and methods in this paper.
