In this study, a fuzzy tuned SMC based architecture is designed for the control of PLL based frequency synthesizers. The proposed approach, offering a continuous tuning of chattering property, is demonstrated to be more effective over classical, intelligent and traditional sliding mode control methods for the fast locking and low phase noise requirements of PLL based frequency synthesizers in frequency hopping spread spectrum communication and radar applications. The obtained simulation results are compared with those of a PID, a Fuzzy Gain Scheduled Control, a SMC, and traditional FS controller design and it has been concluded that the settling time and the phase noise of the frequency synthesizer can be optimized using the developed fuzzy tuned SMC based PLL.
