N2 - Inertia momentum wheel is widely used for satellite attitude-control that requires fine pointing accuracy and stability. But, the inner disturbance torque and noises produced by the inertia momentum wheel seriously deteriorate the output torque precision. Accordingly, this paper adopts the adjustable PID algorithm, regulated by RBF network with a simple disturbance compensator in the torque-mode control system of inertia momentum wheel. Based the dynamics and analysis of disturbance torque, the RBF-PID controller with disturbance compensator are designed. The performance comparisons of the proposed method with conventional PID are performed to show the advantages of the former over the latter on many aspects, such as response time, overshot, anti-disturbance ability, etc.
