高性能新型控制策略与控制结构的研究

New type of high performance control resource and control structure

在对各种控制策略与控制结构进行深入理论研究与仿真实验的基础上,提出自适应逆控制策略及带有干扰观测器的控制策略,是提高系统鲁棒性与抗扰性的最佳结构;对于参数时变造成的对象不确定性及外部干扰,其局部反馈量df可完全予以抵消;控制器Gc(s)只需等于对象模型的逆G-m1(s),并不需等于对象的逆的Gp-1(s)。由该控制策略实现的系统结构简单,具有良好的动、静态性能。

Based on deep research for various control resource and control structure as well as emulation experiment, this paper proposed adaptive inverse control resource and control resource using disturbance observer for the first time, that is the optimal structure to develop robustness and anti-interfere; for uncertain quality and exterior interfere caused by parameter time-varying, the local feedback variable df can be counteracted completely; the controller Gc （s） only need to equal to Gm^-1（s） which is the inverse of object model, not to equal to Gp^-1（ s ） . The system based on that resource possesses simply structure and choiceness dynamic and static capability.
