A microprocessor system of automatic control by pneumatic braking of freight long trains

An algorithm for a microprocessor automatic control system of pneumatic braking of freight trains is presented. Operation in the regime of stabilizing the train speed during its motion during descent and target braking are provided. A proportional differential control law is implemented in the paper. To improve the control quality, it is a good idea to carry out an identification procedure of the parameters of the train braking system. It is shown that the proposed algorithm provides necessary control quality allowing one to prevent deep decreases in velocity and an excess of the available velocity on its stabilization, as well as implementing target braking with acceptable accuracy. © 2014, Allerton Press, Inc.
