Learning outcomes of the course unit
Course absolvent should be an able to design and adjust process controller with standards algorithms. Also to design control algorithms with complicated structures and to implement them into a process computer.
Basic knowledge and concepts of control theory: description of the dynamic system in the Laplace and the Z transformation, stability, dynamics and precision in the steady state. The recommended range of preliminary knowledge is given by the Systems and signals, Control theory - beginers courses. On the course are explained problems by physical control with the help of simple mathematical relationships. Students will deepen significantly and and understand the context by proposal of practical control systems.
