Transformation of CLF to ISS-CLF for Nonlinear Systems with Disturbance and Construction of Nonlinear Robust Controller with L 2 Gain Performance

الملخص EN

A new nonlinear control law for a class of nonlinear systems with disturbance is proposed.

A control law is designed by transforming control Lyapunov function (CLF) to input-to-state stability control Lyapunov function (ISS-CLF).

The transformed CLF satisfies a Hamilton-Jacobi-Isaacs (HJI) equation.

The feedback system by the proposed control law has characteristics of L 2 gain.

Finally, it is shown by a numerical example that the proposed control law makes a controller by feedback linearization robust against disturbance.
