多输入控制系统中目标全息反馈法的极点配置原理

Pole Assignment Mechanism of Nonlinear Control With Objective Holographic Feedbacks for the Multiple-Input Controlled System

在多输入多输出控制系统中,详细论述目标全息反馈非线性控制法(nonlinear control with objective holographic feedbacks,NCOHF)的极点配置原理。在双曲平衡点的邻域内,由于非线性系统与其一次近似系统具有拓扑等价性,因此通过对一次近似系统的讨论,推证出:在多输入系统中,目标全息反馈法可通过极点配置来确保各目标量的准确跟踪和非线性系统的稳定性。以凝汽式发电机组为例,进行极点配置设计,提出目标全息反馈非线性综合控制(nonlinear integrated control with objective holographic feedbacks,NICOHF)规律。仿真结果表明该方法使发电机具有良好的动、静态性能。

Pole assignment mechanism of nonlinear control with objective holographic feedbacks（NCOHF） is discussed for the multiple-inpnt-multiple-outpnt（MIMO） nonlinear system. Due to the topology equivalence between nonlinear system and its linear approximation system near hyperbola equilibrium point, this paper reveals that NCOHF may arrange system poles at the equilibrium point to ensure the precisely track of the interested variables and the stability of nonlinear system by studying the linear approximation system. Furthermore, pole assignment concept is applied for the condensed steam generator set. Therefore, nonlinear integrated control with objective holographic feedbacks（NICOHF） is developed by the pole assignment. Simulation results show that good dynamic and static performances can be achieved for the generator set by employing the NICOHF.
