چکیده
ABSTRACT: Active control is indispensable to electromagnetic suspension system in order to stabilize the open-loop system. For simplicity, linear control strategy is widely utilized in practical maglev systems. However, electromagnetic suspension system is inherently highly nonlinear, which makes linear control strategies sometimes fail in experiments. To conquer the nonlinearity of the suspension system, backstepping algorithm is introduced to the nonlinear model of a magnetic suspension control system in this work. The effectiveness of the proposed controller is verified by simulation, and its suspension performance is discussed under appointed disturbance. The results illustrate that the designed controller based on backstepping strategy can satisfy the performance requirements of the suspension system, and it has fine robustness to disturbance.
