Simulink® Control Design™ lets you design and analyze control systems modeled in Simulink. You can automatically tune arbitrary SISO and MIMO control architectures, including PID controllers. PID autotuning can be deployed to embedded software for automatically computing PID gains in real time.
You can find operating points and compute exact linearizations of Simulink models at various operating conditions. Simulink Control Design provides tools that let you compute simulation-based frequency responses without modifying your model.
Learn the basics of Simulink Control Design
Find model operating point from specification (trimming) or simulation time, initialize model at operating point
Linearize model, visualize linearized system characteristics during simulation
Estimate frequency response and examine frequency-domain characteristics of a Simulink model or a physical plants
Tune PID controllers and other control architectures automatically or interactively
Verify time- and frequency-domain characteristics of linearized models against specified bounds, verify subsystems
