Abstract—The multiple modeling and control approach is a proper method for modeling and control of nonlinear systems which their dynamics changes rapidly at different operating conditions. The dynamic of the twin rotor helicopter in vertical direction is nonlinear and changes instantaneously with respect to change of the elevation angle, and it can be used for implementation of multiple modeling and control approach. In this paper the performance of multiple modeling and control approach by simulation and implementation has been investigated.
