Title:
METHOD AND DEVICE FOR CONTROLLING SAMPLE VALUE
Document Type and Number:
Japanese Patent JPH04133106
Kind Code:
A
Abstract:
PURPOSE:To eliminate the time delay caused by sampling, to execute the response at a high speed, and also, to facilitate the control of high accuracy by outputting output data, at the predicted time when input data reaches a target value. CONSTITUTION:When input data is inputted to an input means 1, a sampling means 3 samples simultaneously this input data and time data of a time measuring means 2, respectively at each time, and stores them in an input data storage means 4. Values of each input data are varied linearly against the time, therefore, when the input data is obtained in two time, respectively, the time for reaching a target value set and stored in advance in a target storage means 5 is predicted, and this value is stored in an output time storage means 7. When the predicted time and the measured time coincide with each other in a comparing means 8, a coincidence signal is outputted immediately to an output means 10, and the contents of a storage means 9 are outputted without waiting the next sampling time.
