摘 要：A novel control scheme is presented in this work to address the attitude stabilization problem in the presence of actuator saturation,misalignment and lack of inertia *** a hyperbolic tangent function in its formulation,the control signal explicitly obeys a known maximum-torque *** the possible actuator misalignment,a dynamic attitude gain is introduced to accommodate the unknown but bounded configuration *** configuration uncertainty assumption is this work is a relatively mild *** saturated controller can be viewed as smooth nonlinear proportional-derivative control *** convergence of the closed-loop attitude system is guaranteed *** have been carried out to demonstrate the effectiveness of the proposed strategy.
