"Fuzzy" based algorithm for a three-point controller

A three-point control algorithm is often applied in thermal power plant control due to its simplicity and inherently bumpless transfer between automatic and manual modes. The paper introduces an alternative concept of three-point controller based on fuzzy logic. Performance of conventional and proposed fuzzy concept are compared by simulation of their operation in subordinated loop of steam temperature control system. The results show that fuzzy three-point controller achieves about the same control quality as the conventional algorithm with considerably smaller switching number of an electromotive actuator.
