摘要: In this paper, a robust adaptive fractional fast terminal sliding mode controller is introduced into the microgyroscope for accurate trajectory tracking control. A new switching manifold defined to ensure finite convergence of system states, where fractional-order differentiation term emerges surface, which additionally generates an extra degree freedom and leads better performance. Adaptive algorithm applied estimate damping stiffness coefficients, angular velocity, upper bound lumped nonlinearities. Numerical simulations are presented exhibit validity proposed method, comparison with other two methods illustrates its superiority.
