Originální abstrakt

In technical practice it shows that the key problem in a PID controller realization is in its derivative part. With an overwhelming majority of compact controllers a continuous transfer function is described in their documentation, even though the implementation is discrete. A replacement of the derivative by first-order difference is unsatisfactory. In order for a PID controller to be practically usable, its derivative action must be filtered. The article discusses multiple ways how the derivative can be implemented in discrete variants of the PID controller. Their respective advantages and pitfalls are compared. One of them, which exhibits responses most similar to the continuous version and is usable in the widest range of sampling periods, is then recommended.
