Application of Virtual Prototyping for Evaluation of Intelligent Active Suspension System

چکیده
This paper presents a methodological approach for the application of virtual prototyping for the evaluation of the intelligent vehicle active suspension system performance. In this approach, a full passenger car model is developed using ADAMS software. In the modeling approach, not only the suspension components are precisely modeled, but also modeling of all systems like steering systems that may affect the suspension performance are taken into account. Moreover, four separate independent fuzzy logic controllers (FLC) are designed based on the quarter car model. The fuzzy controller parameters are then well tuned using genetic algorithm (GA) optimization approach. The vehicle ride evaluation is performed using the interactive MATLAB-ADAMS simulation and the performance of the geneticfuzzy controller is studied. Simulation results show the effectiveness of the approach, resulting in the lower bounce acceleration and the ride quality improvement.

متن کاملOptimal integrated passive/active design of the suspension system using iteration on the Lyapunov equations
In this paper, an iterative technique is proposed to solve linear integrated active/passive design problems. The optimality of active and passive parts leads to the nonlinear algebraic Riccati equation due to the active parameters and some associated additional Lyapunov equations due to the passive parameters. Rather than the solution of the nonlinear algebraic Riccati equation, it is proposed ...
