Fractional order PID control of a radar guided missile under disturbances

This research demonstrates the use of Fractional Order Proportional Integral Derivative (FOPID) system for radar guided missile in order to accurately guide the missile toward its target in the presence of multi noise and error sources such as system delay, radome aberration error and receiver noise. The proposed system is intended to filter out the noises and increase the accuracy of the missile during its flight until it hits its target with minimum miss distance. Genetic Algorithm is used to tune the parameters of the proposed FOPID system. The simulation results demonstrate the effectiveness of the proposed system compared to the conventional system in guiding the missile accurately in the presence receiver noise, system delay and radome aberration error.
