Based on the betterment expert control of the brake cylinder pressure control method

It is obviously that air pressure has the specialties of nonlinear and incertitude, and especially the tiny air pressure is so difficulty to be controlled accurately. A control method of the betterment of expert control is presented to solve these problems. The method uses groovy expert control to define the rules, uses intelligence arithmetic to achieve the dead-time of electric air value and adopts the betterment of expert control arithmetic to implement accurate control on air braking. The method is used in Brake Control Unit and the application result shows that it has excellent static and dynamic specialties and the control precision can achieve 1 kPa. The method can suffice the needs of Brake Control Unit.
