中文摘要
      基于比例-积分-微分(Proportional-Integral-Derivative, PID)的反馈控制是工业过程控制领域首选的基础控制技术. 在PID控制中, 一个看不见的严重缺陷, 即常规积分控制跟踪常值扰动的效率不高的问题已被揭示. 针对常规积分控制存在的问题, 提出了一种无穷阶积分器(infinite order integrator, IOI), 显著提高了跟踪常值扰动的效率. 将IOI等用于构造一种新型反馈控制器(novel feedback controller, NFC), 显著提高了过程输出跟踪过程给定包括跟踪过程稳态偏差的性能. NFC具有简单性和良好的工程易用性, 在难控过程具有比PID更好的控制性能. 数学分析, 仿真实验和电力控制工程应用的结果验证了文中所提出观点和方法的正确性和有效性.
英文摘要
      In industrial process control, Proportional-Integral-Derivative (PID) control is the fundamental technology and first choice for engineers. Rencently, a serious defect of PID that the efficiency of conventional integration control tracking constant disturbances is not high has been revealed. Aiming at this problem of conventional integration control, a infinite orders integrator (IOI) is proposed, can significantly improve the efficiency of tracking constant disturbances, which is a great breakthrough of control engineering. A novel feedback controller (NFC) can be constructed by IOI, which can remarkably improve the performance of the process output tracking set value and steady deviation. NFC has the characteristic with simplicity and practicability in engineering, and it has better control performance on the hard-to-control process than traditional PID. The mathematical analysis, simulation experiments and actual application results on power engineering verify the correctness and effectiveness of the proposed theories and technologies in this paper.
