Adaptive control for non-affine nonlinear systems with input saturation and output dead zone
作者：
Highlights：
• The DSC technique is employed to deal with the “complexity explosion” problem for state-constrained non-affine nonlinear systems subject to output dead zone and input saturation, and the robust compensator is designed to reduce the influences of disturbances and uncertainties.
• The unknown control coefficient derived from output nonlinearity is handled through adopting the property of Nussbaum function.
• A series of barrier Lyapunov functions are designed, which effectively guarantees that prescriptive ranges of system states cannot be violated.
