Stochastic Adaptive Tracking Control of Electronic Throttle

Stochastic adaptive tracking control of electronic throttle is researched in this paper, in which the spring gain and the external load torque are seen as an unknown constant and a Wiener process, respectively. Based on the backstepping technology, a stochastic adaptive tracking control algorithm is given, and the control system is proved to be bounded in probability. Validation of the given tracking controller is proved through numerical simulation. The results of the numerical simulation show that the position of throttle plate can be tracked to its desired value, and the adaptive law can be tuned to a steady value.
