Simulink® Control Design™ lets you design and analyze control systems modeled in Simulink. You can automatically tune PID controller gains to meet performance requirements. You can also automatically tune arbitrary SISO and MIMO control architectures. 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, examine frequency-domain characteristics, validate linearization
Tune PID controllers and other control architectures automatically or interactively
Verify time- and frequency-domain characteristics of linearized models against specified bounds, verify subsystems
