We explore the problem of the control system design of train asynchronous electric traction drives. The proposed train autopiloting contrl system ensures complex optimization of train traction, namely: keeping of desired speed of the wage wheels slippage relative to the rail thus ensuring the maximum traction; minimizes the loss of energy in the power unit of the electric traction drive under changing of speed and power of motion process. In order to solve the stated we use methods and principles of synergetic control theory
