Thrust vectoring is a technology in the aerospace industry that enables an aircraft or rocket to change the magnitude and direction of thrust provided which improve maneuverability, control, and stability. In order to fully utilize the capabilities of thrust vectoring, a capable control system mechanism is essential. This includes implementing a robust controller that can effectively handle uncertainties and disturbances, including changes in the plant configuration within a certain range. The primary focus of this research paper is the development of a robust control system for 3-DOF thrust vectoring, employing the μ-synthesis technique. The study revolves around iteratively designing a robust controller to meet specific performance criteria. The key design requirements include stability, noise attenuation, disturbance rejection, and precise tracking of step changes in the X and Z directions. The controller design must also consider physical actuator constraints, with a maximum gimbal deflection angle of 0.5 radians and a delta thrust limit of 10 Newtons to ensure safety and feasibility. The Simulink simulation analyzes the closed-loop response of a nonlinear plant to tracking commands in both X and Y directions. The simulation result shows that the system remains stable under various uncertainties. The controller effectively tracks commands despite noise, wind gusts, and uncertainties in density, thrust source, and horizontal center of gravity keeping the delta thrust and gimbal deflection angle within specified limits. Simulation results demonstrate its robustness, ensuring stability and reliability for real-world applications.
