The purpose of this bachelor thesis - GUI for PID controllers design was to create in MATLAB a simple GUI (Graphical User Interface) for PID (Proportional{Integral{De- rivative) controllers design and tuning. The design method is usable for any linear system, where we know a plant model - its transfer function. It's based on a frequency design methods, which use the shaping of the open-loop transfer function in the Nyquist diagram according to the phase or gain margin entered by user. The designed PID controllers should satisfy all the speci�c user requirements, especially the speci�ed phase or gain margin and the desired maximum steady error to a unit step or ramp of a desired setpoint. The result of the controller design is a graphical visualization of a plane with para- meters values of the controller, which satisfy all these requirements. A part of the GUI is also a display of step and frequency responses for the concrete selected parameters values of the controller.
