Robust Linear Controller Design for Attitude Control of a Rocket

Attitude control of the rocket is a big challenge in real-time. To make the rocket stable against the influences, this book has examined the control technology such as proportional integral derivative control using an anti-windup mechanism and linear quadratic regulator theory based on the degree of freedom mathematical model. The transient behaviour of both controllers is not smooth and takes more time to settle in the defined location. Specific to the deficiencies of PID and LQR, the proportional integral derivative controller is combined with a fuzzy logic controller to overcome the defects of PID and LQR. In conclusion, this book compares the performance analysis of fuzzy-PID controllers with linear quadratic regulators and proportional integral derivative controllers. The simulation results indicate that the hybrid fuzzy-PID controller has a remarkable improvement in terms of overshoot and settling time besides reducing steady-state error. The proposed hybrid fuzzy-PID controller eliminates the overshoot completely and produces enormous stability for the rocket engine.
