Tune a PID controller for plants that cannot be linearized. You use the PID Tuner to identify a plant for a buck converter. Then tune the PID controller using the identified plant.
Design a PI controller with frequency response estimated from a plant built in Simulink. This is an alternative PID design workflow when the linearized plant model is invalid for PID design
Design an array of PID controllers for a nonlinear plant in Simulink that operates over a wide range of operating points.
Use Online PID Tuner block to tune a PI controller of an engine speed control system in both simulation and real time.
