| Abstract |
With respect fo the variing nonlinearity of a line commutated inverter the precalculating algorithm for a dc motor current control has been developed and implemented. Possible real time firing instants alpha(n) are on line examined ahead of real time to obtain a corresponding future mean value Id**(n). Comparing this future current mean value Id**(n) to the desired set point ld ref, firing instants may be derived exactly. Id**(n) will result from future current shape id**(T ,n), which is calculated in the signalprocessor using on line numerical integration of the armature differential equation. Repetetive use of the above precalculation of Id**(n) will yield a real time current controller with ideal step response no matter if the converter is operared in continuous or discontinuous mode. |
