Optimalization of Controllers
FEKT-LOPRAcad. year: 2019/2020
he course is focused on modern methods of analysis and design of control systems. In the centre of interest are adaptive systems, design of optimal control, predictive controllers and using artificial intelligence in control algorithms.
Learning outcomes of the course unit
Become familiar with different approaches used by theoretical and especially practical solution in modern control theory. The student of the course can handle implementation of discrete variants of PID controllers with two degrees of freedom, adaptive controllers, optimal controllers, fuzzy controllers, and the use of neural networks in control algorithms. Also he is able to optimize their parameters settings.
The subject knowledge on the Bachelor´s degree level is requested.

The aim of this subject is to formulate engineering problem as an optimization task, to find a solution and correctly interpret formulated problem. This process will be outlined using the classical and modern methods which are employed in the theory of automatic control. The basis for comparison are the discrete variants of PID controllers and their optimal settings of parameters. Modern methods represent adaptive, optimal and predictive controllers and the methodology for their implementation and settings. Artificial intelligence methods include fuzzy controllers and neural networks and their implementation methodology of settings his parameters.
