Adaptive Fuzzy Controller Design for Networked Control Systems with Delay Compensation Approach Mohammad Khademi mohammad khademi@ec iut ac ir 2019 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Assist Prof Marzieh Kamali m kamali@cc iut ac ir Prof Farid Sheykholeslam sheikh@cc iut ac irAbstract Networked control systems NCSs have been one of the main research focuses in academia as well as inindustry for many decades and have become a multidisciplinary area The NCSs play a prominent role in reduc ing the industrial control system expenditures improving system efficiency enhancing reliability facilitating thedistinction and recognition of failure and simplifying the maintenance method In order to exchange information reference input plant output control input etc among the control system components sensor controller actuator etc the shared network is utilized It is noteworthy to state that there are several constraints in NCSssuch as time delays packet lose data quantization and network security Time delay as one of the main con straints in NCSs can be dealt through distinct approaches such as model predictive controller Adaptive buffering Smith predictive adaptive fuzzy controller In this study the NCS and controller design in NCSs accompaniedby input delay and output constraint has been presented One of the proposed approaches in this dissertation isbackstepping control in which an auxiliary signal compensated time delay The uncertain non linear functionshave been estimated by fuzzy logic systems Furthermore The barrier lyapunov function would compensate theoutput constraint Add to that the explosion of complexity in backstepping approach is also observed whichcould be solved by dynamic surface control In comparison with the backstepping control approach designingthe dynamic surface controller leads to the simplification of virtual control signals In addition the designedcontroller performance has been illustrated by means of simulated examples KeyWords Networked Control Systems Time Delay Adaptive Fuzzy Controller Backstepping Control Approach Dynamic Surface Control Approach
