Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1] [2] that improves a vehicle's stability by detecting and reducing loss of traction . [3]
Every control system must guarantee first the stability of the closed-loop behavior. For linear systems , this can be obtained by directly placing the poles. Nonlinear control systems use specific theories (normally based on Aleksandr Lyapunov 's Theory) to ensure stability without regard to the inner dynamics of the system.
Multiple studies have found electronic stability control systems tend to reduce fatal collisions, particularly single-vehicle and rollover crashes. Since 2012, the NHTSA has mandated that all new ...
Vehicle Dynamics Integrated Management (VDIM) is an integrated vehicle handling and software control system developed by Toyota. It involves an omnibus computer linkage of traction control, electronic stability control, electronic steering, and other systems, with the intent of improving responsiveness to driver input, performance, and overall ...
An active rollover protection (ARP), is a system that recognizes impending rollover and selectively applies brakes to resist. [1]ARP builds on electronic stability control and its three chassis control systems already on the vehicle – anti-lock braking system, traction control and yaw control.
This is a technique used as a stability criterion in the field of classical control theory developed by Walter R. Evans which can determine stability of the system. The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter (see pole–zero plot).
This made ISS the dominating stability paradigm in nonlinear control theory, with such diverse applications as robotics, mechatronics, systems biology, electrical and aerospace engineering, to name a few. The notion of ISS was introduced for systems described by ordinary differential equations by Eduardo Sontag in 1989. [7]
In control theory, and especially stability theory, a stability criterion establishes when a system is stable. A number of stability criteria are in common use: Circle criterion; Jury stability criterion; Liénard–Chipart criterion; Nyquist stability criterion; Routh–Hurwitz stability criterion; Vakhitov–Kolokolov stability criterion
