Research on the Control Algorithm of EPS for Vehicle Handling Stability

摘要

Based on the problem of the Control Algorithm in the electric power steering (EPS) system, a current controller of EPS for vehicle handling stability is designed. The dynamic models of EPS and the vehicle were constructed, simplifying the evaluation system of vehicle handling stability, putting forward an EPS designed controller that has H_∞ mixed sensibility based on the evaluation index of vehicle handling stability. The test results indicate that the designed controller for EPS shows a favorable handling performance, it also could effectively restrain the noises and disturbances caused by sensors and road conditions. The designed controller has robust stability and performance, and can effectively in prove the handling stability and safety of vehicles.
