NON-LINEAR ELEMENT CORRESPONDENCE ARITHMETIC UNIT

摘要

PROBLEM TO BE SOLVED: To attain high speed and high accuracy operation for a non-linear element in real time by switching an internal variable to be used for matrix operation for an input value based on a status space method to a linear element variable stored correspondingly to each section of the operation in each change of the section of the operation during the execution of the matrix operation. ;SOLUTION: Simultaneously with the forced end of matrix operation being executed at the head of periodical interruption (S41), the output value of just preceding matrix operation is read out from a data buffer and processed (S42). Then matrix operation (S4) and characteristic switching processing (S35) are alternately started again by using the data buffer and a new input matrix value. When the processing (S35) is not settled or is not generated, the matrix operation (S4) continuously outputs the same output result until the generation of a succeeding periodical interruption (S41). Consequently the output value of a control or dummy element including a non-linear element to be finally required can be accurately calculated.;COPYRIGHT: (C)1999,JPO
