Title:
METHOD AND APPARATUS FOR CONTROLLING ANTI-YAW DAMPER
Document Type and Number:
WIPO Patent Application WO/2020/211266
Kind Code:
A1
Abstract:
Provided is a method for controlling an anti-yaw damper. The method comprises: acquiring a transverse acceleration signal of a framework, and carrying out first preprocessing on the transverse acceleration signal; acquiring the pressure difference between two piston cavities of an anti-yaw damper, and carrying out second preprocessing on the pressure difference; obtaining, according to a first preprocessing result and a second preprocessing result, an MPPT algorithm target function value of the current moment and an MPPT algorithm target function value of the previous moment, and comparing the MPPT algorithm target function value of the current moment with the MPPT algorithm target function value of the previous moment; and controlling, according to a comparison result, an adjustment direction of an electromagnetic proportional valve of the anti-yaw damper. According to the method, a damping force of an anti-yaw damper can be adjusted in real time, thereby improving the adaptability of the damper in different wheel wear states and the kinetic stability of a motor train unit. Also provided is an apparatus for controlling an anti-yaw damper.
