研究基于侵入与不变流形(I&I)自适应方法和非线性干扰观测器(NDO)的可逆冷带轧机速度张力系统耗敞Hamiltou控制问题.首先采用I&I自适应方法估计系统的摄动参数;其次,通过预反馈建立系统速度张力外环的耗散Hamilton模型,并利用互联和阻尼配置以及能量整形方法设计耗散Hamilton控制器;再次,选用NDO对系统电流内环的外扰进行观测,并引入设计的积分滑模控制器中进行补偿;最后将该方法应用于某1 422mm可逆冷带轧机速度张力系统中进行仿真,结果验证了所提出方法的有效性.
In this paper, the open Hamlineou control problem of velocity-tension system of reversing cold strip mill based on invading and invariant manifold (I & I) adaptive method and nonlinear disturbance observer (NDO) is studied. Firstly, I / I adaptive method is used to estimate the perturbation parameters of the system. Secondly, a dissipative Hamiltonian model of the outer ring of the system tension tension is established by pre-feedback, and the dissipative Hamilton controller is designed by using the interconnection and damping configuration and the energy shaping method. Thirdly, NDO is used to observe the external disturbances of the system inner loop and Finally, the method is applied to a 1222mm reversible cold rolling mill speed tension system simulation, the results verify the effectiveness of the proposed method.
