The invention discloses a control method of a variable rotor rotating speed helicopter. The variable rotor rotating speed helicopter is provided with a continuous stepless speed change transmission mechanism and a turboshaft engine with variable power turbine rotating speed. The control method comprises steps, firstly, calculating the required power of the helicopter according to the atmospheric environment, the forward flight speed and the rotor speed; calculating engine performance parameters of the turboshaft engine under the condition of a certain power turbine rotating speed according tothe helicopter required power; and finally, taking the engine performance parameters as initial guessing values, and taking variable speed distribution factors as optimization variables, carrying outoptimization solution on a helicopter/engine comprehensive system performance calculation model of the variable rotor rotating speed helicopter, and controlling the continuous stepless speed change transmission mechanism and the power turbine according to the solved optimal variable speed distribution factors. The invention further discloses a control device of the variable rotor rotating speed helicopter. The optimal rotor rotating speed and the optimal power turbine rotating speed can be obtained at the same time, and the comprehensive performance of a helicopter/engine system is remarkablyimproved.
