The Energy Regeneration of Electromagnetic Energy Saving Active Suspension in Full Vehicle with Neurofuzzy Controller

Abstract

To improve the vehicle performance such as ride comfort and road handling, the active suspension system should be used. However, the current active suspension system has a high energy consumption therefore reducing the fuel economy. In this paper the vibration excited by road unevenness is treated as a source of mechanical energy. It is being converted into electrical energy to compensate for the energy consumption by the active suspension. To achieve this task, an electromagnetic active suspension system has been introduced. The power generated from this device has been used as input power of the pump of the hydraulic actuators. Adaptive neuro-fuzzy controllers have been designed to generate a signal to control the valves of the hydraulic actuators.

A comprehensive comparison of the vehicle vibration energy harvesting abilities of the regenerative shock absorbers predicted by the quarter, half and full vehicle suspension system models

“…Abdelkareem et al [38] analyzed the potential of energy harvesting using a full VSS model. Control system has also been developed based on the full VSS model integrated with the RSAs [39]. Despite of its advance in accuracy, there are only a few researches applying the full VSS model due to its complexity.…”

Synthesis of active compensation system of spring oscillation in two–mass electromechanical object

“…Ввиду простоты реализации наибольшее применение последний способ получил в системах подрессоривания транспортных средств [8][9][10]. Используемые при этом регуляторы синтезируются путем решения задачи АКР [8] или на основе наперед заданных баз правил [9], реализуют нейро-нечеткие законы управления.…”

“…Используя указанную выше аналогию, можно утверждать, что для обеспечения инвариантности объекта (5) к изменению параметров необходимо организовать скользящий режим, при котором управляющее воздействие e F принимает значения, заданные выражениями (9). Такой скользящий режим можно сформировать, если потребовать, чтобы переключения управляющего воздействия e F компенсировали первое слагаемое второго уравнения системы (5).…”

Vibration Energy Harvesting on Vehicle Suspension Using Rotary and Linear Electromagnetic Generator

“…The employing of recovered energy from vibration to control the vibration itself is investigated by [5]. Reference [6], purpose Neuro-fuzzy Controller for actuate hydraulic valve using electromagnetic energy recovery for full car model. Performance of suspension for road and ride holding were presented by [7].…”
