چکیده
To improve the handling stability of automobiles and reduce odds rollover, active or semi-active suspension systems are usually used to control roll a vehicle. However, these kinds often take zero-roll-angle as target have limited effect on improving performance vehicle when turning. Tilt control, which actively controls tilt inward during curve, greatly benefits comprehensive it is cornering. After analyzing advantages disadvantages strategies for narrow commuter vehicles by combining structure dynamic characteristics automobiles, direct (DTC) strategy was determined be more suitable automobiles. A model predictive controller DTC designed based an suspension. This allowed reverse cause moment generated gravity offset that centrifugal force, thereby significantly stability, ride comfort, speed, rollover prevention. The simultaneously tracked desired angle yaw rate, achieving path tracking while anti-rollover capability Simulations step-steering input double-lane change maneuvers were performed. results showed that, compared with traditional proposed reduced occupant’s perceived lateral acceleration load transfer ratio turned exhibited good path-tracking performance.

Semi-Active Suspension Control Using "Fast" Model-Predictive Techniques
The problem considered in this paper is the design and analysis of a control strategy, for semi-active suspensions in road vehicles, based on Model Predictive Control (MPC) techniques. The optimal control law we compute using predictive techniques aims to optimize, the suspension performance, by minimizing a quadratic cost function while ensuring that the magnitude of the forces generated by th...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولA Robust Predictive Control Design for Nonlinear Active Suspension Systems
This paper proposes a novel method for designing robust nonlinear multivariable predictive control for nonlinear active suspension systems via the Takagi-Sugeno fuzzy approach. The controller design is converted to a convex optimization problem with linear matrix inequality constraints. The stability of the control system is achieved by the use of terminal constraints, in particular the Constra...
