Abstract :
Based on the conception of relative-degree of differential geometry theory on nonlinear system, nonlinear disturbance decoupling control on travelling crane electro-hydraulic servo system with dual cylinder was studied. Through define relative-degree of disturbance vectors on the nonlinear system, the sufficient condition of system disturbance decoupling was provided. Then a differential geometry decoupling control approach was presented. The actual application results show that the proposed controller has better tracking and synchronization performance than conventional PID controller.
