摘要： A method of calculating a motor position uses a hall sensor. The method can include determining a motor position in response to a signal change of a hall sensor installed to a motor, calculating a basic compensation value for compensating a motor position error due to signal measurement delay of the hall sensor, determining whether a current command condition for a constant-speed operation of the motor is satisfied, calculating a first-up compensation value and a first-down compensation value, calculating an average values of the deviation between d-q axes current commands, and correcting the motor position using the basic compensation value when a difference between the average values is less than a reference average value.

摘要： A measurement system includes a receiver configured to receive a measurement signal indicative of a parameter of a measured object. The measurement system also includes a processor configured to iteratively filter the measurement signal using a threshold value. The processor is also configured to adjust the threshold value for each iteration of filtration and determine a signal-to-noise ratio for each iteration of filtration. The processor is also configured to set a filter threshold value to the threshold value for the iteration based on the signal-to-noise ratio.

摘要： A method for correcting offset drift in a sensor used in cyclic sensing is provided. The method includes: identifying a target value for a parameter of a signal between sensing cycles of the sensor; ascertaining a difference between a measured value for the signal and the target value; ascertaining a duration between the sensing cycles; using the difference and the duration, calculating a number of steps to attain the target value from the measured value; and adjusting the measured value by the number of steps to substantially agree with the target value. A pressure sensor is disclosed.

摘要： A method of interfacing an LC sensor with a control unit is described. The control unit may include first and second contacts, and the LC sensor may be connected between the first and second contacts. The method may include starting the oscillation of the LC sensor, and monitoring the voltage at the second contact, in which the voltage at the second contact corresponds to the sum of the voltage at the first contact and the voltage at the LC sensor. The voltage at the first contact may be varied such that the voltage at the second contact does not exceed an upper voltage threshold and does not fall below a lower voltage threshold.

摘要： The measurement system having multiple sensors for sensing the same physical magnitude comprises at least one set of n redundant sensors or of models representing the same physical magnitude in order to deliver n measurement signals, a fusion unit for performing fusion that is the result of multiplexing the n measurement signals in order to deliver a single multiplexed output signal resulting from the fusion of the n measurement signals, and a reconditioned UKF receiving the multiplexed output signal to output a signal constituting the best estimate of the measurement of the physical magnitude after rejecting signals representative of a sensor failure.

摘要： A physical quantity measuring apparatus of the present invention measures a physical quantity from a signal based on a physical quantity output by a physical quantity signal output apparatus. A correction signal output unit outputs a new correction signal based on a signal on the basis of a physical quantity obtained at a given measurement time, a correction signal obtained before that measurement time, and a filter coefficient. A large/small relationship determining unit determines a large/small relationship between the signal on the basis of the physical quantity and the correction signal obtained before that measurement time. A first filter coefficient output unit outputs a first filter coefficient based on the plural large/small relationships.

摘要： The disclosure relates to mitigating the effect of a sudden change in sensor calibration parameters. An embodiment of the disclosure retrieves a current calibration parameter value for the sensor, determines a new calibration parameter value for the sensor, and generates transitional calibration parameter values based at least on the current calibration parameter value and the new calibration parameter value using an interpolation function configured to prevent a sudden change in the sensor calibration parameter values.

摘要： In a position detection device, an amplitude modulation is executed for AC excitation signals Sc using modulation wave signals. Differential amplifiers execute a voltage conversion of the modulated wave signal Sin, Cos to digital data SIN, COS and transmit them to a microcomputer. The microcomputer multiplies the modulated wave signals SIN, COS with parameters cos φ, sin φ, and executes a subtraction of the multiplied value to obtain an error-correlation value ε. An angle calculations section in the microcomputer receives a detected value εc obtained by multiplying the error-correlation value ε with a binary detection signal Rd. The binary detection signal Rd corresponds to a positive sign or a negative sign of the signal Sc. It is adjusted that the sampling number of samples of the signal Rd corresponding to a positive value is equal to that corresponding to a negative value during one period of the signal Sc.
