Research on the Computers Assistance Recurrence Identification of Hollow Cylinder Specimen Shaped Testing Apparatus

Briefly introduces the overall structure and loading principle of the hollow cylinder specimen testing apparatus, and the importance of its modelling necessary for the quantitative analysis under continuously loading conditions, and also describes the principle of on-line real time modelling of a random, time-varying and nonlinear system by use of recurrence augmented matrix least squares technique based on IBM-PC/XT computer. The configuration of the hardware of the identification system and the technique adopted in the software design for improving identification speed and accuracy are also given. Finally, the application of the system to the apparatus and its actual control effect are discussed.
