There exists a positive constant \({Y_D}\) such that \(\left( {{y_d},{{\dot{y}}_d},{{\ddot{y}}_d}} \right)\) belongs to the compact \({\Omega _y}\), where \({\Omega _y} = \left\{ {\left( {{y_d},{{\dot{y}}_d},{{\ddot{y}}_d}} \right) :y_d^2...
Adaptive on-time control (D-CAP? mode) is able to dynamically adjust the on-time duration based on the input voltage, output voltage, and load current so that it can achieve relative constant frequency operation. It not only inherits the merit of ripple mode control scheme mentioned above, ...
The present invention discloses an adaptive constant ON time adjustment circuit, which generates a square wave signal having a constant normal ON time during normal operation, for controlling a power stage circuit to convert an input voltage to an output voltage. When the output voltage is shifted...

At each control interval, the adaptive MPC controller updates the plant model and nominal conditions. Once updated, the model and conditions remain constant over the prediction horizon. If you can predict how the plant and nominal conditions vary in the future, you can useTime-Varying MPCto spec...
we rely on an approach that is very often used to avoid problems with the estimation of constant parameters. This approach consists in the introduction of artificial dynamics in the parameters, that means the parameters are allowed to slightly change their values over time. In this way, and in...
In [7], an adaptive ILC was proposed by using the same time-differential parameter adaptation law as that of adaptive control directly. However it is limited to constant parametric uncertain systems only. In [8], [9], a new adaptive ILC was developed for time-varying parametric systems by ...
The Temporal High-pass Filtering Nonuniformity Correction (THPF-NUC) algorithm has three major drawbacks, namely only correcting the offset coefficient, difficulty in choosing a proper time constant and unclear detail of corrected image. By analyzing the time constant’s effect on the correction qualit...
