Abstract. Research of the automatic control system properties with fuzzy regulator, which includes fuzzy pseudo-linear correction device with phase advance and PID regulator is provides in this One alternative method of building object control and regulation systems that are fuzzy defined in terms of classical theory is the use of o-called fuzzy ogic controllers.
Therefore, the development of fuzzy control regulators on the basis of existing microcontrollers is a very urgent task, as a pseudo-linear fuzzy regulator based on fuzzy sets and fuzzy logical input/output, in the condition of uncertainty of the disturbing effect, is able to provide higher performance of the ransient process than the traditional PID regulator.
As pseudo-linear correction devices (PCCs) we use: CD with amplitude suppression, with phase advance and with separate channels for amplitude and phase, as one of the main disadvantages of PID regulator is the presence of phase delay and high sensitivity to interference in the measurement channel.
