Abstract

The invention discloses an RBF (Radial Basis Function) sliding mode variable structure control-based vehicle ISD (Inerter-Spring-Damper) suspension active control method. The method includes the following steps that: (1) a suspension controlled and ideal reference model is established; (2) a tracking error vector is defined; 3) a switching surface function is designed; and (4) an approach law is determined; and (5) an RBF neural network is applied to optimize sliding mode variable structure control. With the RBF sliding mode variable structure control-based vehicle ISD suspension active control method of the invention adopted, an ISD suspension system with a simple structure can track the output of a complex ideal ISD suspension model, so that the overall performance of a suspension can beimproved. With the method adopted, a new research idea and direction are provided for the design and application of a vehicle ISD suspension, especially for the study of a controllable ISD suspension.

Description

technical field [0001] The invention belongs to the field of vehicle suspension system control, in particular to the control of vehicle ISD (Inerter-Spring-Damper) suspension system using an inerter device. The invention relates to a control method of a vehicle ISD suspension, in particular to a vehicle ISD suspension control method using an electromechanical inerter. Background technique [0002] The inerter is a new type of two-point mechanical element, and its force is proportional to the relative acceleration. Different from the single-terminal characteristics of mass components, inerters do not need to ground any endpoints. Therefore, the proposal of inerters realizes a strict correspondence between mechanical network components and circuit network components. Vehicle ISD suspension is a new suspension vibration isolation system composed of "Inerter-Spring-Damper" (Inerter-Spring-Damper). Vehicle ISD suspension breaks the constraint of the traditional two-element para...
