Design methods for feedback controllers of nonlinear systems based on EB and virtual optimization approaches

The two types of design methods for nonlinear control systems have been proposed. One is based on the analytical approach, where a nonlinear controller is constructed through the energy balancing (EB) passivity-based control, and the other is based on the numerical approach, where a nonlinear controller is numerically approximated through a virtual optimal control algorithm, Moreover, those two methods are demonstrated to be efficient in the nonlinear situation through the design problem of a jet engine compressor model.
