Example: "The car is equipped with an auxiliary drive to improve fuel efficiency during long trips."
Alternatives: "secondary drive" or "supplementary drive".
Then, an augmented auxiliary drive signal is constructed in order to breakthrough the observer rank condition.
An auxiliary drive signal vector which may satisfy the observer matching condition is constructed.
An augmented drive system used to deal with channel noise is constructed by introducing a new auxiliary drive variable.
Based on a kind of nonsingular transformation for the state and output of augmented auxiliary drive system, a reduced-order observer is designed to asymptotically estimate the states of the augmented auxiliary drive system, and a high-gain sliding-mode observer is considered to estimate the augmented auxiliary drive signal and its derivative.
The coordinated control problem that occurs when HHMAS operates in the auxiliary drive mode is addressed in this paper; the solution to this problem is the key to the maximization of HHMAS.
By using the drive signals of original system, a step-by-step sliding mode observer is considered to obtain the exact estimates of the auxiliary drive signals and their derivatives.
Remove the camshaft, balancer shafts, and auxiliary drives.
The auxiliary turbine drives the main boiler feed pump and, optionally, an auxiliary generator which could carry away the power surplus generated by the system to the unit transformer through separate, additional primary coils.
Moreover, utilizing the auxiliary system driven by the difference between saturated torque and command torque, a backstepping control law, which satisfies the input saturation constraint and guarantees the spacecraft stability, is presented.
Try unplugging everything from the power supply except for the motherboard such as CD/DVD drives, hard drives, auxiliary power to your video card etc.
