Method and device for selecting bus capacitor capacitance value of electric control suspension controller

Abstract

The invention provides an electric control suspension controller bus capacitor capacitance value selection method and device, and the method comprises the steps: generating a simulation model of an electric control suspension controller, enabling a simulation model to operate according to a target rotating speed and a target current which are set by a user, and selecting the capacitance value of abus capacitor by using a particle swarm algorithm in the operation process of the simulation model. Whether the selection of the capacitance value of the bus capacitor is proper or not is studied bytesting the simulation model of the electric control suspension controller, and compared with a conventional method for determining the capacitance value of the bus capacitor by testing through an actual sample piece, the method shortens the selection period, and reduces the cost; and bus capacitance selection is carried out by using a particle swarm algorithm, so that the simulation efficiency isgreatly improved.

Problems solved by technology

If empirical values ​​are used or the capacitance of the bus capacitor is selected to meet the design requirements, when the capacitor type is determined, the larger the capacitance, the more capacitors are required, which not only increases the cost, but also increases the layout space of the circuit board.

At present, the actual sample is tested to determine the capacitance of the bus capacitor. The selection of the bus capacitor generally undergoes a complex process of estimation, verification, modification, and verification. Increased time and labor costs
