Automotive industry is growing widely and rapidly by the involving of multi-fields not only mechanical engineering but also electrical and electronic engineering, material and more. As a key system in vehicles, suspension system and its control have been studied for a long time. A well-controlled suspension system provides high vehicle handling, good drivability and high comfort for passengers, and good isolation from road noise and vibration. To enhance comfort and handling of light-weight vehicles, semi-active suspension system is considered and proposed by numbers of papers. A semi-active suspension features small system space, low complexity and easy maintenance. Therefore, it is suitable for small compact car body known as light vehicles. This paper focuses on the analysis and control of a semi-active suspension for light-weight vehicles. Models of a quarter-car suspension with air spring and magneto rheological damper were built. Because components in the system involve nonlinear dynamic characteristics, a self-tuning Fuzzy logic controller was designed. Simulation results showed that the designed suspension system with its controller had good performance in vibration suppression.

This paper focuses on the analysis and control of a semi-active suspension for light-weight vehicles with small compact car body. The suspension was chosen due to its small system space, low complexity and easy maintenance. A new magneto rheological damper was designed and validated by computer simulation. After that, models of a quarter-car suspension with air spring and the new damper were built. Due to the nonlinear dynamic phenomena of system components, a self-tuning fuzzy logic controller was developed. Simulation results showed that the designed suspension system with its controller had good performance in vibration suppression on various operation conditions.

In this paper, a control system is designed for a vehicle active suspension system. In particular, a novel terminal sliding-mode-based fault-tolerant control strategy is presented for the control problem of a nonlinear quarter-car suspension model in the presence of model uncertainties, unknown external disturbances, and actuator failures. The adaptation algorithms are introduced to obviate the need for prior information of the bounds of faults in actuators and uncertainties in the model of the active suspension system. The finite-time convergence of the closed-loop system trajectories is proved by Lyapunov's stability theorem under the suggested control method. Finally, detailed simulations are presented to demonstrate the efficacy and implementation of the developed control strategy.

Suspension Model

Vehicle suspension is a MIMO coupling nonlinear system; its vibration couples that of the tires. When magneto-rheological dampers are adopted to attenuate vibration of the sprung mass, the damping forces of the dampers need to be distributed. For the suspension without decoupling, the vibration attenuation is difficult to be controlled precisely. In order to attenuate the vibration of the vehicle effectively, a nonlinear full vehicle semi-active suspension model is proposed. Considering the realization of the control of magneto-rheological dampers, a hysteretic polynomial damper model is adopted. A differential geometry approach is used to decouple the nonlinear suspension system, so that the wheels and sprung mass become independent linear subsystems and independent to each other. A control rule of vibration attenuation is designed, by which the control current applied to the magneto-rheological damper is calculated, and used for the decoupled suspension system. The simulations show that the acceleration of the sprung mass is attenuated greatly, which indicates that the control algorithm is effective and the hysteretic polynomial damper model is practicable.
