Command-filter-based adaptive tracking control for nonlinear systems with unknown input quantization and mismatching disturbances

作者：

Highlights：

• This paper investigates the adaptive tracking control problem for a class of uncertain nonlinear systems with input quantization and mismatching disturbances.

• The effect of the mismatching disturbances is compensated by introducing smooth functions in the virtual controllers.

• By combining the novel command filters and backstepping method, a novel adaptive controller is designed to solve the problem above.
