Abstract: In this study, an extended SIMC PID controller is designed for an unstable angle of attack of a FOXTROT aircraft and then its stability is tested for a particular range of perturbation values. The robust stability for the above system is tested analytically and graphically using Kharitonov Stability Criterion. Further, it was established that not only the designed controller along with the plant is stable but also robust stable while the aircraft flies with different speed.
