Problems solved by technology

However, this results in additional production costs and involves complex and complex production and installation
[0006] The disadvantage is therefore that a high manufacturing and / or installation and / or cost outlay is usually required for an approximation of the true value (for example with other sensors) if the measured variable cannot be measured directly by the sensor
Another disadvantage is that, in the prior art, deviations from the true value are often not determined with sufficient precision

Embodiment Construction

[0066] In a subsequent figure, different embodiments use the same reference numerals to represent the same technical features.

[0067] exist figure 1 with figure 2 The electric kitchen multi-purpose machine 10 is shown schematically. The electric kitchen multi-purpose machine 10 includes a housing 20 having accommodating seat 22 for stirring the container 24. The agitating container 24 is, for example, by a cover 21, and preferably has a handle 23. The mixer 51 and / or the heating element 53, in particular with the heating element of the heating plate 53.1, and / or at least one sensor 52 preferably temperature sensor 52 is preferably disposed in the region of the stirring container 24. Especially in this mixer 51, in particular the knife is disposed within the agitation container 24. Preferably, the sensor 52 is disposed outside the interior space of the agitating container 24, for example, in a region of the heating element 53 or the heating plate 53.1 or is disposed on the st...

Abstract

The invention relates to a method (100) for estimating (150) a time-varying measured variable of a system, in particular the temperature in a container (24), preferably in an electric kitchen appliance In (10), the electric kitchen multi-purpose machine is used to prepare food at least partially automatically, wherein at least one measurement information (210.1) is determined by measurement, the measurement information is different from the measurement parameter at least according to at least one system parameter (230) the true value of .

Description

Technical field [0001] The present invention relates to a method of detailed definitions in the preamble of claim 1. Background technique [0002] The purpose of the measurement is usually a prediction regarding quantization of measurement parameters. Usually in this case, the measured value is deviated from the true value of the measurement parameters, wherein the deviation is negligible in most cases or can be deducted in a simple manner. It is also known that the use of physical models is used to calculate or estimate the true value according to at least one measured value. The impact needed for this, especially system parameters, usually well known, can be estimated or negligible. [0003] However, the problem is often, however, the status or system parameters of the dynamic system during the dynamic process cannot be directly determined and / or only incompletely observe. It is particularly problematic that the measurement parameters of the (dynamic) system can vary over tim...
