Satellite multitasking fuzzy system for attitude and sun tracking

Almost all high-precision pointing satellites use reaction wheels to produce the desired commanded control torque to stabilize their pointing direction. The reaction wheels are good actuators; however, one or two wheels may fail sometimes and could jeopardize the space missions. The solar arrays in...
