实时 PID 自动调节

使用被控对象频率响应进行 PID 增益的实时无模型调节

PID 自动调节可用于针对物理被控对象实时调节 PID 控制器。如果您有 Simulink^® Coder™ 等代码生成产品，则可以生成在硬件上实现调节算法的代码，以允许您在环路中使用或不使用 Simulink 进行调节。要快速入门，请参阅How PID Autotuning Works。

When to Use PID Autotuning
PID autotuning lets you tune a PID controller without a parametric plant model or an initial controller design. Deploy the algorithm to tune a controller in real time for a physical plant.
How PID Autotuning Works
To use PID autotuning, configure and deploy a PID autotuner block. The block injects test signals into your plant and tunes PID gains based on an estimated frequency response.
PID Autotuning for a Plant Modeled in Simulink
Use the PID autotuning algorithm to tune against a plant modeled in Simulink while the model is running.
PID Autotuning in Real Time
Deploy the PID autotuning algorithm as a standalone application for real-time tuning against your physical system.
Control Real-Time PID Autotuning in Simulink
Run the PID algorithm against your physical plant while controlling the tuning process in Simulink.
Tune PID Controller in Real Time Using Closed-Loop PID Autotuner Block
Tune a single-loop PID controller in real time by injecting sinusoidal perturbation signals at the plant input and measuring the plant output during a closed-loop experiment.
Tune PID Controller in Real Time Using Open-Loop PID Autotuner Block
Tune a single-loop PID controller in real time by injecting sinusoidal perturbation signals at the plant input and measuring the plant output during an open-loop experiment.
