Type: conference-paper
Abstract: A mathematical model of the automatic control system with a combined fuzzy PD controller has been developed. The blurring of the P - component of control has been carried out based on three linguistic variables of the normalized error signal. The fuzzy control described by the fuzzy base of rules has been given, membership functions have been chosen, and their parameters have been adjusted, a synthesis and analysis of a hybrid robust system having a simplified rule base with a fuzzy PD-controller for objects with variable parameters has been carried out, a simulator of the system has been designed. For the convenience of adjustment and research of separate blocks and system visualization blocks have been provided. An example of synthesis and modeling of a combined fuzzy system for inertial objects of the third and fourth order has been considered. The settings for adjusting the controller have been defined and adjusted. The results of simulation modeling in the form of transient characteristics for objects of different dimensions that satisfy the specified parameters of quality control and provide better quality indicators than with a traditional controller have been given, and the results of simulation modeling have been presented.
