Such controllers include time-varying functions or non-smooth functions such as a sign function [5 12].

Meanwhile, a continuous function is applied to replace a sign function to reduce the variable structure control (VSC) chattering.

The error may be positive or negative decided by a rule of sign function.

To resolve the chattering problem caused by the discontinuous sign function, a modified continuous output feedback controller is proposed by introducing functions with continuous property.

The proposed sliding mode control strategy eliminated the chattering phenomenon by replacing the sign function with a saturation function, and by replacing the constant coefficients in the reaching law with adaptive ones.

By introducing sign function and necessarily modifying the method of adding a power integrator, a state feedback controller is successfully constructed to preserve the equilibrium at the origin and guarantee the global asymptotic stability of the resulting closed-loop system.

Furthermore by adding an integrator and incorporating a saturation function in the control law, the chattering phenomenon caused by the sign function is avoided.
