چکیده
A 2-DOF vehicle active suspension system model with time-delay feedback control is established. The stability region of the obtained by using Routh-Hurwitz criterion and polynomial discriminant theory. multi-objective optimization function established taking into account ride comfort, driving safety, handling stability, optimal parameters are particle swarm optimization(PSO) algorithm. vibration characteristics systems under different road excitations studied through experiments simulations then compared passive uncontrolled based on LQR. experimental results show that sprung mass acceleration(SMA) harmonic excitation reduced 58.02% 39.18% to LQR system, respectively. Meanwhile, acceleration random has a 69.56% 35.50% reduction performance controlled better than in numerical study experiment. Moreover, simulation good consistency, which proves reliability results.

Bifurcation analysis in active control system with time delay feedback
In this study, a model of active control system with time delay feedback is investigated, and time delays were set in control loop. An efficient method was used to analyze the stability of the system. By solving the characteristic equation, the local stability and the existence of codimension one bifurcation (Hopf bifurcation and fold bifurcation) were obtained. Regarding the time delay as bifu...
متن کاملDistributed Backstepping Control With Actuator Delay For Active Suspension System
The actuator time delay problem for a linear active suspension system using the theory of backstepping control design is examined in this study. Time-delay may arise in active suspension systems because of transport phenomenons, information processing, sensors or some mechanical reasons. Designing the controller without taking into account the actuator time delay may degrade the performance of ...
