Liu S., Zhou H., Luo X., Xiao J. Adaptive sliding fault tolerant control for nonlinear uncertain active suspension systems. 2.3. This paper proposes a novel actuator of the active HIS system. The active suspension system is developed through sliding mode control for a quarter car model. In the last few decades, significant progress has been made in the field of Process Control and instrumentation and offers a unique controller named CRONE, which is a noninteger controller to ascertaining the solution of the system under various model uncertainties. Active suspension systems are multivariable dynamic systems for which it is difficult to derive mathematical models. Most seat suspension systems have passive dampers, but this active seat suspension has good passive performance without a damper. (1996). At the same time, the spring stiffness is carefully chosen to ensure that … Abdolvahab Agharkakli, Ghobad Shafiei Sabet, Armin Barouz,2012, “Simulation and Analysis of Passive and Active Suspensions System Using Quarter Car Model for Different Road Profile,” International Journal of Engineering Trends and Technology, Vol 3 Issue 5. Therefore, analytical control schemes based on such models are complex to construct and generally do not perform well in practice. Research has focused on determining how to achieve the optimal suspension performance: namely, ride comfort, road handling, and suspension deflection. Thanks to the development of the advanced actuators and control techniques in last few decades, active suspension systems becomes more promising and are being actively researched in both academia and industry [, , , ]. For Figure .1 Passive suspension componentIt was shown that active suspension system had a better potential to improve both the ride comfort and road holding, since the acceleration has been reduced for active CM system (19.58%) and for active ADM system (34.08%) compared to passive one [2]. The actuator consists of two cylinders, a ball screw, and only one motor. IFAC-Papers OnLine, Vol. Active suspension of vehicle systems using fuzzy logic. Active fuzzy control design for suspensions system The proposed algorithm was applied to design a half-car fuzzy control-based active suspension system as a test bed. Search Google Scholar for this author, Juing-Shian Chiou. Therefore, a semi-active suspension system is the effective way to improve the suspension system and has been widely investigated [6, 8, 15, 20]. To control active suspension with preview information, a device that maps the front terrain of the running vehicle must be developed. A novel electromagnetic active suspension with an energy-regenerative structure is proposed to solve the suspension’s control consumption problem. [3] Figure 1. Active suspension systems can effectively improve vehicle handling characteristics and provide good passenger comfort. 1. Rollover prevention is always one of the research hotspots in vehicle design.

Semi-active suspension system can reduce the hazards on the way even after huge jerking due to road mishaps. 1629-1666. The closed loop model of the fuzzy logic controller for the vehicle suspension system is presented in Fig.2. Ming-Yuan Shieh. The active suspension system involves multiple complex technical problems, such as mechanology material science and electronics. The simulated results plotted in the time domain and root mean square values. Control Engineering Practice, Vol. The use of the two gear reducers makes this active suspension׳s internal friction force larger than that in normal seat suspensions and this enables the vibration energy to dissipate. 36, No. Juing-Shian Chiou.
