Active anti-roll bar control using electronic servo valve hydraulic damper on single unit heavy vehicle

Comparison between LQR and ANN Active Anti-Roll Control of a Single Unit Heavy Vehicle

Heavy-duty Vehicle Rollover Detection and Active Roll Control

The safety of road vehicles depends on the yaw-roll dynamics. A loss of roll stability results in a rollover accident. Mechanisms to warn against rollover threat and a rollover avoidance control methodology are crucial in designing a successful active safety warning/control system for heavy-duty commercial vehicles. A dynamic rollover metric, Time-To-Rollover (TTR), has become popular in rollov...

Electro-hydraulic Servo Valve Systems

Hydraulic systems driven by servo valves provide highly accurate control over enormous forces. A servo valve system consists of a transducer, a servo amplifier, a servo valve, and an actuator with a connected load. It is a closed-loop system used for the precise control of the output (load) parameter, such as position, velocity, or force, in response to a command signal. The output is converted...

Semi-active H∞/LPV control for an industrial hydraulic damper

In this paper, a new control strategy is developed to improve comfort and roadholding of a ground vehicle equipped with an industrial damper. This damper can be controlled by means of a small servomechanism which adjusts the damping rate. The main controller is a linear parameter varying (LPV ) static state-feedback controller synthesized in the H∞/LPV framework to compute the required damping ...

Modeling and Control of a New 1/4t Servo-hydraulic Vehicle Active Suspension System

Nowadays, the active suspension is the key technology for vehicles to achieve both ride comfort and control performance. In this paper, a new 1/4T servo-hydraulic vehicle active suspension system is developed and two control schemes are utilized. The first one is a conventional PID controller obtained from Ziegler-Nichols method and the second one is the neural network controller. Though these ...
