"This paper presents a static output feedback sliding\r\nmode control method to regulate a two-wheeled inverted pendulum\r\nsystem with considerations of matched and unmatched\r\nuncertainties. A sliding surface is designed and the associated\r\nsliding motion stability is analysed based on the reduced-order\r\ndynamics. A static output sliding mode control law is synthesised\r\nto drive the system to the sliding surface and maintain a sliding\r\nmotion afterwards. The nonlinear bounds on the uncertainties\r\nare employed in the stability analysis and control design to\r\nimprove the robustness. The simulation results demonstrate the\r\neffectiveness of the proposed control."^^ . . . . .
