My bachelor thesis is divided into two parts. The first part is focused on the creation collection procedures for the designing of PID controllers and Lead-Lag types of controllers by frequency methods satisfying the demands of value phase margins. Filed procedures for the designing of the controllers were used to create two functions in MATLAB environment. From the specified transfer function describing a dynamic system, and phase margin, the constants of regulators will be calculated by using frequnecy method.

The second part of my bachelor thesis is focused on a comparing of conduct of designed controllers on systems with different dynamics in terms of its quality (the parameters of compensation, noise suppression, robustness). This second part is determined to be used for the discussion of benefits of more sophisticated methods of the Lead- Lag designed controllers.
