摘要

A non-linear PID controller based on single-point suspension system was designed at first in this paper, and it was analyzed that its gain is higher than that of linear PID controller with little error. It is indicated by simulation that the dynamic performance of closed-loop system was satisfying when its load changed, so its robust performance of non-linear PID controller is better than that of PID controller. Refined computation of levitation damping was discussed according to robust observer, which included normalization and digital processing of input signals. It was validated by experiment that single-bogy system can be stabilized by using the non-linear PID controller and damping designed in this paper, and the vehicle-coupledguideway vibration was restrained, which proved that computation method of damping in this paper is correctly.
