Actuator Mechanism Using Suspension-wire for 2D Scanning

Linear control of car suspension using nonlinear actuator control

In classic passive suspension design, comfort and road handling are conflicting design criteria. An active or semi-active suspension offers the possibility to vary the damper characteristics along with the road profile. Such systems have discrete settings or are limited in bandwidth up to 10Hz. This paper discusses the development of a controller for a passenger car using a recently developed a...

Numerical Survey of Vibrational Model for Third Aircraft based on HR Suspension System Actuator Using Two Bee Algorithm Objective Functions

This research explains airplane model with two vertical vibrations for airframe and landing gear system. The purpose of this work is to advance vibrational model for study of adjustable vibration absorber and to plan Proportional-Integration-Derivative approach for adapting semi active control force. The coefficients of this method are modified as stated by Bee multiobjective optimization using...

Sliding Mode Control for Active Suspension System with Actuator Delay

Sliding mode controller for a vehicle active suspension system is designed in this study. The widely used quarter car model is preferred and it is aimed to improve the ride comfort of the passengers. The effect of the actuator time delay, which may arise due to the information processing, sensors or actuator dynamics, is also taken into account during the design of the controller. A sliding mod...

Distributed 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 ...
