Abstract
The passivity-based control (PBC) is a new direction of nonlinear control. But the method is basically a qualitative method. A quantifiable design method in combination with the PBC is provided in the paper. To solve the special partial differential equation (PDE) for PBC, the nonlinear system needs to be firstly transferred to a Hamiltonian model. The PDE for the Hamiltonian system was solved with an electromagnetic levitation example. The passivity-based control law was also presented and discussed. The proposed method provides a practical design tool for the nonlinear control.
