control of switched linear input delayed systems with fuzzy pid gain scheduling approach

This paper deals with fuzzy pid gain scheduling control of switched linear systems with input delay. since, designing a model based controller for switched systems has special difficulties, in this paper, the non model based controller fuzzy pid gain scheduling is introduced to perform the stability analysis and control design of switched linear systems. the actuator delay is an inherent characteristic of many mechanical devices. therefore, the actuator lag is considered in system modelling and control design. fuzzy rules and reasoning are employed online to calculate the pid gains and based on the error signal and its first derivative. the ziegler nichols method is used to set the initial values of pid control gains. simulation results are presented to show the effectiveness of the proposed approach. it will be shown that this controller significantly has a better performance compared with the conventional pid controller with fixed parameters.
