MEASUREMENT TESTING DEVICE

PURPOSE:To attain a solution at a simulation time with the same accuracy as a digital computer by comparing data recorded on a recording means with data obtained by measuring input/output at the operation time after substitution due to a calculating means. CONSTITUTION:Since the output of an input/output device of a calculator 18, namely, a servo amplifier 3 inputted to an analog input signal processing part 9 and the output of an analog output signal processing part 11 are given to a data comparator 8 through a signal line 20a and a signal line 20b respectively, they are compared with the reproduced output of an input/output data recorder 7. In case of this comparison, setting of a digital variable setter 15 and a wiring 19 are controlled properly until input/output signals of the calculator 18 and the output of the input/output data recorder 7 coincide with each other. When the reproduced output of the input/output data recorder 7 and input and output signals of the calculator 18 coincide approximately with each other in the data comparator 8 as the result of this control, simulation is approximately complete, and its mathematical model and parameters are performance parameters of a servo motor 4 and a position detector 5.
