동적 차수 보정법을 이용한 고차 적분 시스템의 안정화

This paper considers the stabilization problem of power integrator systems. After designing an augmented system, a dynamic smooth controller is designed by using dynamic exponent scaling and backstepping techniques. The designed controller renders the origin of the closed-loop system globally exponentially stable. Since the controller may have a singularity problem, the recently developed ‘degree indicator’ is adopted to avoid this problem.
