In this paper, an adaptive PID-Fuzzy Logic controller is proposed in order to control the angular displacement of an automobile Pierburg mechatronic actuator and achieve a wireless network control. This new PID-fuzzy logic controller topology takes advantage of the classical PID controller and the fuzzy logic technique which can improve the angular displacement precision and reduce the time delay caused by the wireless communication in the control loop. Different from other fuzzy PID controllers, our PID controller is located before the fuzzy controller and acts as its inputs. A mathematical analysis and the advantages of the designed controller are discussed. The proposed PID-Fuzzy Logic controller achieves the control task reducing the steady-state error and the time delay. Experimentation results of the wireless control are presented exhibiting good performances.
