The quest to increase the performance of rail car in terms of stability, safety and ride comfort has triggered research into the design, modelling and dynamic simulation of the suspension system of a rail car using advanced control
Suspension systems have been widely applied to the modern automobile and rail cars with complex control algorithms to reduce the effects of vertical acceleration caused by road disturbances (Ulum, Affaf, & Suparwanto, 2017; Yao & Shi, 2013)
Summary
There has been widespread interest in the use of advance control and automation techniques to optimize the performance of the suspension system of a rail car (Al-Zughaibi and Davis, 2015; Bideleh & Berbyuk, 2016). The electronically controlled active suspension system can potentially improve ride comfort as well as the road handling and vehicle stability especially for racing car (Kim, Choi, & Lee, 2014; Oh et al, 2016). Semi-active and active suspension systems are considered as new technologies that are used to improve ride quality and handling of the vehicle with the semi-active suspension system showing some similarities with the conventional suspension system This kind of suspension has a spring and controllable damper in which the spring element is used to store the energy the controllable damper is used to dissipate the energy. Some of the semi-active suspension systems use the passive damper and the controllable spring, the controllable damper usually acts with limited capability to produce a controlled force when dissipating energy (Hrovat, 1990; Nguyen, Choi, & Nguyen, 2014). The advantage of semi-active system is that the cost of operation is less than the other type of advanced suspension system (Oraby, Aly, El-Demerdash, & Selim, 2007)
