控制设计

使用 Simulink^® Control Design™ 软件对模型和设计控制系统进行线性化

要设计和分析在 Simulink 环境中建模的控制系统，请考虑使用 Simulink Control Design 软件。

Simulink Control Design 扩展 Simulink，使您能够找到各个工作点，并计算 Simulink 模型在不同工况下的精确线性化。Simulink Control Design 提供工具让您计算基于仿真的频率响应而无需修改模型。

Simulink Control Design 提供了几种调节 Simulink 模块（例如 Transfer Function 和 PID Controller 模块）的方法。您可以使用这些方法和工具来：

自动调节包含 PID Controller 或 PID Controller (2DOF) 模块的反馈环。
以图形方式或自动方式调节包含任何可调 Simulink 模块的 SISO 反馈环路。
调节具有任何结构的控制系统的 Simulink 模型，以满足高级设计目标，如参考跟踪、抗扰和稳定裕度。
