Abstract

To improve the dynamic response of the parallel AC/DC transmission system, constructive nonlinear control designation has been introduced into the typical nonlinear system. In according to the diversity of nonlinear phenomena, lots of nonlinear controls are proposed. The constructive nonlinear control using the dissipativity and passivity concept can guarantee the stability and robustness of the system. Aiming to two generator systems, which interconnected with AC/DC line, the equation of the model is given. And by constructing the output and input of the system, the system can be proven to be passive. The control law promises the Lypunov stability too. The simulation results are based two disturbance cases, and show the effectiveness of the control
