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]
Optimal control is a particular control technique in which the control signal optimizes a certain "cost index": for example, in the case of a satellite, the jet thrusts needed to bring it to desired trajectory that consume the least amount of fuel. Two optimal control design methods have been widely used in industrial applications, as it has ...
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
The Nyquist plot for () = + + with s = jω.. In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [] at Siemens in 1930 [1] [2] [3] and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, [4] is a graphical technique ...
Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder and servo) and wheel-speed sensors with ABS. The basic idea behind the need for a traction control system is the loss of road grip can compromise steering control and stability of vehicles.
Car manufacturer Stellantis is recalling 211,581 SUVs and pickup trucks over a software malfunction that could cause their electronic stability control systems to fail.
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 ...
In the control system theory, the Routh–Hurwitz stability criterion is a mathematical test that is a necessary and sufficient condition for the stability of a linear time-invariant (LTI) dynamical system or control system. A stable system is one whose output signal is bounded; the position, velocity or energy do not increase to infinity as ...
