Synergetic Design of Autopiloting Systems with Complex Optimization of Train Traction

In the paper we explore the problem of design of the control system of train asynchronous electric traction drives with regard to transitional processes in the wheel-rail contact. In this system, the wheels can slip relative to the rail, and the excessive slippage has a negative effect on the train traction properties and increases the wear of the wheel pair and rail surface. A new approach to the synthesis of train traction regulators is proposed that is based on the theory of synergetic control. The proposed train autopiloting regulator 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. The last feature provides, in turn, the maximum rate of energy efficiency during operation.
