Active Suspension Support Vector Machine Generalized Inverse Composite Controller and Its Construction Method

Abstract

The invention discloses an active suspension support vector machine generalized compound inverse controller and a construction method thereof. The controller comprises an active suspension system, an optimal controller and a linear motor support vector machine generalized composite inverse controller. The construction method includes forming a compound control target by cascading a current inverter before a linear motor, forming a support vector machine inverse system by the support vector machine and two integration elements, and combining a linear controller with the support vector machine inverse system and the current inverter to form the support vector machine generalized compound inverse controller. A sensor of the active suspension system is used for extracting suspension vibration signals online, and the optional controller is used for calculating the optimal control force and the vibration velocity. The support vector machine compound inverse controller controls the linear motor to output corresponding electromagnetic force and velocity in real time according to the control force and the suspension vibration velocity given by the optimal controller and the electromagnetic thrust and velocity fed back by the linear motor, thereby realizing system linearization, decoupling and degree reduction while achieving good effect and real-time performance of the active suspension.
