ABSTRACT: Based on the feedback
linearization technique, we present a systematic design method for the General Integral Control and a new integral
control strategy along with a class of fire-new integrator. By using the linear system theory and Lyapunov method along with LaSalle’s
invariance principle, the conditions on the control gains to ensure regionally
as well as semi-globally asymptotic stability are provided. Theoretical analysis
and simulation results demonstrated that: by using this design method, General Integral Control can deal with
nonlinearity and uncertainties of dynamics more effectively; the optimum response can be achieved in the
whole control domain, even under uncertain payload and varying-time disturbances.
This means that General Integral Control has strong robustness, fast convergence,
good flexibility, and then makes the engineers design a high performance
controller more easily.
