摘要：
This paper investigates the problem of nonlinear systems with input saturation and unknown bounded time-varying external uncertainties. We introduce an appropriate clipping function to represent input saturation and make the saturation model continuously differentiable. Robust deterministic control based on transformation function is creatively proposed to achieve global practical stability and suppress the nonlinearity caused by approximation error, external disturbances, and saturation. The control is applied to the turbofan engine model, and its effectiveness is illustrated by the numerical simulation.
