增益调度

调节非线性被控对象增益调度控制器

增益调度控制器的增益会作为时间、工况或被控对象参数的函数自动调整。增益调度是其动态特性随时间或工况而变化的控制系统的常用策略。这种系统包括线性参数变化 (LPV) 系统和若干大类非线性系统类。要在 MATLAB^® 或 Simulink^® 中调节增益调度控制器，您可以使用 tunableSurface 命令将可变增益表示为调度变量的函数。有关调节增益调度控制器的工作流概述，请参阅Gain Scheduling Basics。

Parameterize Gain Schedules
A gain surface parameterizes a variable gain in terms of the scheduling variables. Use gain surfaces to model variable gains in a gain-scheduled control system.
Change Requirements with Operating Condition
When tuning gain-scheduled controllers, you can specify tuning objectives that depend on the scheduling variables.
Validate Gain-Scheduled Control Systems
Tuning gain-scheduled controllers guarantees suitable performance only near each design point. It is important to validate the tuning results over the full range of operating conditions.
