连续搅拌反应釜的非线性H_∞控制

Nonlinear H_∞ control of continuous stirred tank reactor

以连续搅拌反应釜(CSTR)为例,研究了非线性系统存在控制量约束时的H∞控制问题,基于Hamilton Jacobi不等式,得到了系统的L2增益有限的充分条件,在这个条件下,得到了使闭环系统满足H∞扰动衰减性能准则的状态反馈控制器.

*' With the example of CSTR system, the H∞ control problem of nonlinear systems with control constraints is studied. Based on HamitonJacobi inequality, a sufficient condition is presented such that its L2gain is limitable. Under the condition, a state feedback controller which is satisfied with disturbance attenuation performance is given.
