Abstract
An evaluation system for evaluating a flow rate of a fluid coming from a tank, the system including measurement device suitable for measuring a fluid level in the tank and including estimation device for estimating the flow rate of the fluid using an unscented Kalman filter, the estimation device including an obtaining device for obtaining the raw fluid flow rate and correction device connected to the obtaining device and to the measurement device and configured to correct the raw flow rate as obtained by the obtaining device as a function of the level measured by the measurement device. A method performed by such a system.
Claims12
An evaluation method for evaluating a flow rate of a fluid coming from a tank, the method comprising measuring a level of the fluid yk in the tank and a step of estimating the flow rate of the fluid {circumflex over (d)}k by using an unscented Kalman filter, said step of estimating comprising a step of obtaining the raw fluid flow rate {circumflex over (q)}k and, when a level measurement yk is available, a correcting step of correcting the obtained raw flow rate as a function of the level measurement.
An evaluation system for evaluating a flow rate of a fluid coming from a tank, the system comprising measurement means suitable for measuring a fluid level yk in the tank and estimation means for estimating the flow rate {circumflex over (d)}k of the fluid using an unscented Kalman filter, said estimation means comprising obtaining means for obtaining the raw fluid flow rate and correction means connected to the obtaining means and to the measurement means and configured to correct the raw flow rate as obtained by the obtaining means as a function of the level yk measured by the measurement means.
