Some Simulink blocks, such as those with sharpdiscontinuities, 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.
If you cannot find a good design using PID Tuner, try a different PID controller type. If no PID controller is satisfactory, consider designing a more complex controller.
Most process controllers sold today incorporate auto-tuning functions. Operating details vary between manufacturers but all follow rules similar to those described above. Essentially, the PID controller “learns” how the process responds to a disturbance or change in.

- PID Tuning Basics. Choose a Control Design Approach. Simulink Control Design provides several approaches to tuning Simulink blocks, such as Transfer Fcn and PID Controller blocks. Introduction to Model-Based PID Tuning in Simulink. Use PID Tuner for interactive tuning of PID gains in a Simulink model containing a PID Controller or PID Controller (2DOF) block.
- System Architecture of PID Controller PID is closed-loop system, we need a feedback from DC motor. Therefore, to use PID control, DC motor need to has an encoder. Encoder will output the signal, which is used to calculated the real position and speed. The calculation of position and speed is performed by DC motor controller.
When you run your Simulink model using the PIDgains computed by PID Tuner, the simulation output can differ fromthe PID Tuner response plot.
When you run your Simulink model using the PIDgains computed by PID Tuner, the simulation output may not meet yourdesign requirements.
If controller performance deteriorates when you discretizea tuned continuous-time PID controller, consider tuning a discrete-timecontroller directly.
Pid Tuning Methods
When you use PID Tuner to design a controller, theresulting derivative gain can have a different sign from the integralgain. PID Tuner always returns a stable controller, even if one ormore gains are negative.
