Induction motor structures in DC electrified railways with their dynamic performance are studied. Characteristics of the current, voltage, electrical and mechanical torque and active and reactive power in accelerating, normal and regenerative braking are investigated. The characteristics of the induction motors used for Tabriz urban railway are simulated with PSCAD/EMTDC software proving the in...
This work exposes a largely unexplored vector of physical-layer attacks with demonstrated consequences in automobiles. By modifying the physical environment around analog sensors such as Antilock Braking Systems (ABS), we exploit weaknesses in wheel speed sensors so that a malicious attacker can inject arbitrary measurements to the ABS computer which in turn can cause lifethreatening situations...
In road vehicles, wheel locking can be prevented by means of closedloop Anti-lock Braking Systems (ABS). Two output measured variables are usually considered for regulation: wheeldeceleration and wheel longitudinal slip. The traditional controlled variable used in ABS is the wheel deceleration, since it can be easily measured with a simple wheel encoder; however, it can be dynamically critical ...
In designing the anti-lock braking system (ABS), some states and parameters of vehicle system such as road friction of coefficient and wheel slip should be estimated due to lack of cost effective and reliable sensors for direct measurement. Because of nonlinear characteristics of vehicle dynamics and tire forces, development of a nonlinear estimation algorithm is necessary. However, considerati...
در این پایان نامه بخش های مختلف سیستم ترمز ضد قفل ((abs)anti-lock braking system) شرح داده شده و قسمت های الکتریکی و الکترونیکی آنرا به صورت مفصل تری مورد بررسی قرار گرفته اند. سپس یک کارت اکتساب داده (مدل pci-1711u) تهیه و بر روی یک رایانه نصب و با وصل کردن ترمینال های آن کارت به بخش های مختلف abs از جمله سنسورهای سرعت چرخ، شیرهای الکتروهیدرولیکی، پدال و ...، داده های یک abs واقعی که بر روی...
