gain scheduling -凯发k8网页登录

gain scheduling is a common technique for controlling nonlinear systems with dynamics changing from one operating condition to another. gain scheduling is used when a single set of controller gains does not provide desired performance and stability throughout the entire range of operating conditions for the plant.

designing a gain-scheduled controller typically involves the following steps:

1. linearize nonlinear plant model at different operating conditions to obtain linear models that describe plant behavior in the vicinity of the operating point that a linear model corresponds to.
2. tune controller gains for all the linear plant models.
3. implement a gain-scheduled controller architecture, where controller gains are “scheduled” with a scheduling variable, such as a measured output or a system state.
