The pendulums' equations are linearized around the equilibrium point, while the arm equation is linearized by the integral sliding-mode algorithm based on the stability theory of Lyapunov function. The total system is finally changed into a linear time-invariant system with an input which is related to the integrand of the integral sliding function and designed by the pole placement. Three cases, including different initial pendulum angles, uncertain mass or length of pendulum and external noise, are simulated to check the robustness of the proposed controller and are compared with traditional linear controller. From the simulation, it is clear that integral sliding mode controller is more robust than the traditional linear controller.
