Simulink Control Design提供调整Simulink块的几种方法,例如金宝app转移FCN.andPID控制器blocks.
Introduction to Model-Based PID Tuning in Simulink
使用PID调谐器在包含a的Simulink模型中的PID增益的交互式调整金宝appPID控制器orPID控制器(2DOF)块。
调整PID控制器以减少参考跟踪的过冲或改善植物输入的干扰拒绝。
当您在一个或多个开放模型引用的模型中从控制器块打开PID调谐器时,请指定线性化和调谐的顶级模型。
默认情况下,PID调谐器将工厂线性化,并在Simulink模型中初始条件指定的操作点设计一个控制器。金宝app有时,此操作点与要设计控制器的操作点不同。
Design PID Controller from Plant Frequency-Response Data
当您的工厂模型没有线性化时,一个选项是基于模拟频率响应数据设计PID控制器。Simulink Control Design给你几种方法来做。
Interactively Estimate Plant from Measured or Simulated Response Data
For plants that do not linearize, if you have System Identification Toolbox™ software, PID Tuner lets you estimate the parameters of a linear plant model based on time-domain response data. You can then tune a PID controller for the resulting estimated model.
Design Family of PID Controllers for Multiple Operating Points
如果您的非线性Simulink模型在金宝app各种操作条件下运行,可以为多个模型操作点设计一系列PID控制器。
Implement Gain-Scheduled PID Controllers
要使用PID控制器系列实现增益计划控件,请创建一个与相应的PID增益相关联的查找表。
Design Two-Degree-of-Freedom PID Controllers
调PID控制器(2DOF)块实现良好的设定点跟踪和良好的干扰抑制。
Specify PI-D and I-PD Controllers
PI-D and I-PD controllers are used to mitigate the influence of changes in the reference signal on the control signal. These controllers are variants of the 2DOF PID controller.
Plant Cannot Be Linearized or Linearizes to Zero
一些仿真软金宝app件模块,比如那些锋利的说continuities, can produce poor linearization results. For example, when your model operates in a region away from the point of discontinuity, the linearization of the block is zero.
Cannot Find a Good Design in PID Tuner
如果您无法使用PID调谐器找到良好的设计,请尝试不同的PID控制器类型。如果没有PID控制器令人满意,请考虑设计更复杂的控制器。
When you run your Simulink model using the PID gains computed by PID Tuner, the simulation output can differ from the PID Tuner response plot.
使用PID调谐器计算的PID增益运行金宝appSIMULINK模型时,模拟输出可能无法满足您的设计要求。
如果控制器性能使调谐的连续时间PID控制器离散时劣化,请考虑直接调谐离散时间控制器。
When Tuning the PID Controller, the D Gain Has a Different Sign from the I Gain
当您使用PID调谐器设计控制器时,产生的导数增益可以具有来自积分增益的不同符号。PID调谐器始终返回一个稳定的控制器,即使一个或多个收益为负。
