Improved data sensing and estimation

Improved data sensing and estimation. A system or method for determining virtual data of a system, relative to a measurement point having a sensor located nearby, is determined by a controller. The system calculates modeled data at the measurement point, filters the modeled data to determine filtered data, and calculates a differential between the modeled data and the filtered data to determine acompensation term. The system also determines raw-sensed data from the sensor at the measurement point, and combines that raw-sensed data with the compensation data to calculate the virtual data at the measurement point. In some configurations, the modeled data is determined from a physics-based model. Furthermore, filtering the modeled data may include using a low-pass filter, and a time constantfor the low-pass filter may be calculated based on operating conditions of the system. 本发明涉及改进的数据感测和估计。一种用于相对于具有位于附近的传感器的测量点确定系统的虚拟数据的系统或方法，由控制器确定。系统计算在测量点处的建模数据，滤波建模数据以确定滤波数据，和计算建模数据与滤波数据之间的差异以确定补偿项。系统还由在测量点处的传感器确定原始感测数据，和将该
