Computer Aided Generation of Microprocessor Software for Controlling Static Power Converters

An expert systems based automatic control software generator for the Programmable Logic Controller

“…Given the system specification, the elementary states that define all actions to be done in every moment and the necessary control matrices are generated [1].…”

“…An operation with a multiple input function and two single input functions may have upto two physical conditions, but these physical conditions may only precede the multiple input function. Operands N umber of bi t to be tested (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) Memory location of word to be operated on (V, \VY)…”

“…N umber of bi t to be set N umber of bi ts to be moved (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) Memory location of word to be rotated (V, \VY)…”

“…Number of times the 4-Bit segments are to be rotated (1)(2)(3) Memory location of one word to be acted upon (TCC, TCP, DSC, DSP, DCP, V, \VX, \VY) Memory location of second word to be acted upon (TCC, TCP, DSC, DSP, DCP, V, \VX, \VY) In the case of instructions, devices, and functions the first two most significant digits represent the type of device, instruction, or function, the remaining two digits are the hexadecimal representation of the number of the device, instruction, or function. In the case of memory address location the most significant digit indicates the starting address location and the remaining three digits indicated the offset.…”
