双容时滞系统二次优化控制的非线性化设计
Nonlinearized Design for Twice-optimal Control of a Second-order Dead-time System
摘要
Abstract
We present a new nonlinearized design method for a second-order dead-time system with optimal control.First,on the basis of the twice-optimal control theory of the second-order dead-time system,we construct a system infinite-dimensional state observer and verify that the observer can eliminate the impact of time delay on the system and has strong robustness.Second,to improve the rapidity of the system,we apply a squareroot amplifier to nonlinearize the system.Finally,we illustrate a nonlinear example and a comparative study.Results show that the new system has not only a fast and smooth tracking response but also strong robustness to load the disturbance and the parameter perturbation.The new method has strong applicability and is easy to implement.关键词
