中文摘要
      本文对[1]提出的非线性PID控制系统进行了深入的分析,探讨了系统鲁棒性的原因,并在理论分析的基础上提出了一种新的非线性微分器。仿真结果表明,由改进微分器构成的非线性PID控制系统比采用文[1]的办法具有更强的鲁棒性和适应性,而且对反馈回路的噪声有更强的抑制能力。
英文摘要
      In this paper, the nonlinear PID control system designed with direct method in [1] is analyzed theoretically combined with simulation. The robustness of the system is also investigated. A new nonlinear differentiator is also proposed, based on the theoretical analysis. Simulation comparison shows the improved differentiator has stronger ability to reject the noise in the feedback channel. So the nonlinear PID control system with the improved differentiator is more robust and more adaptive than with the original one.
