Vehicle Active Suspension Control Method Based on Dynamic Model and Improved GA Algorithm
In response to the lack of adaptability to complex dynamic environments in traditional suspension systems,the study first designed a dynamic model and road surface model of the suspension system.Then,migration and global search strategies were in-troduced into the GA algorithm.Finally,an active suspension control method was designed based on the dynamic model and improved GA algorithm.The simulation results show that the root mean square of pitch angle acceleration and pitch angle acceleration of this method are reduced by 26.9％and 21.3％respectively compared to passive suspension systems,and by 20.8％and 27.0％respec-tively compared to self disturbance anti suspension control systems.The root mean square of the three performance indicators such as centroid displacement of this method are 40.6％,41.4％,and 42.9％lower than those of the passive suspension system,respective-ly.It has been proven that when the design method is applied to vehicles,the smoothness and stability of the vehicle are good,provi-ding strong support for the development and application of vehicle suspension control technology.
