This paper proposed a concise nonlinear fin roll control derived from integrator backstepping with nonlinear damping term. The resulting backstepping-based controller consists two parts, first part is a PID controller which agrees very well with the concise robust close-loop gain shaping algorithm (CGSA). While the second part is a nonlinear compensation which can be simplified by leaving the high order nonlinear terms out of consideration in no high-accuracy conditions. Therefore, the controller proposed has a concise structure, definite design procedure and strong robustness, facilitates the actual application.
