【摘要】 考虑一类带有不确定性的单输入-单输出时滞非线性系统,利用反步设计的迭代设计思想,在每一步构造一个李亚普诺夫-克拉索夫斯基泛函,用放大不等式的方法获得一种鲁棒控制器表达式。该控制器保证闭环系统是一致最终有界的。最后,以二阶的连续搅拌化学反应器为例的仿真结果,验证了控制器具有良好的控制特性。更多还原

【Abstract】 In this paper,a class of single input single output time-delay nonlinear systems with uncertainty is considered.Based on an iterative procedure known as backstepping,the Lyapunov-Krasovskii functionals are constructed at each step.By magnifying inequation at each step,a robust controller expression can be acquired,and the uniformly ultimately boundedness of the closed loop system can be guaranteed.A practice industry process-a two stage CSTR has been provided to illustrate the application of the main result.The simulation shows that the controller proposed in this paper has well control behavior.更多还原
