Abstract

Przedmiotem wynalazku jest sposób korekcji pochodnych czasu narastania i czasu opadania prądu w procesie sterowania wysokoobrotowego silnika reluktancyjnego oraz układ przeznaczony do realizacji tego sposobu mający zastosowanie w elektrycznych urządzeniach napędowych. Sposób korekcji pochodnych czasu narastania i czasu opadania prądu polega na tym, że symultanicznie z procesem wyznaczania wartości pochodnej czasu narastania oraz wartości pochodnej czasu opadania prądu dokonuje się korekcji bieżącej wartości pochodnej poprzez dobór wartości sygnału kompensującego proporcjonalnego do iloczynu aktualnej wartości prądu w uzwojeniu, prędkości obrotowej wirnika oraz co najmniej jednego dobieranego parametru stałego. Układ do korekcji pochodnej czasu narastania i czasu opadania prądu ma blok mnożący (11), którego wejścia połączone są z blokiem kontrolno-sterującym (1), blokiem parametrów stałych (12) oraz poprzez filtr górno-przepustowy (10) z rezystorem pomiarowym RP prądu roboczego silnika, natomiast wyjście bloku mnożącego (11) połączone jest z blokiem wyznaczania pochodnej ujemnej prądu (7) i poprzez inwertor (13), z blokiem wyznaczania pochodnej dodatniej prądu (6).The subject of the invention is a method of correction of time rise and fall time derivatives in the process of controlling a high-speed reluctance motor and a system designed to implement this method applicable in electric drive devices. The method of correction of the rise time and fall time derivatives is that simultaneously with the process of determining the rise time derivative value and the fall time derivative value, the current derivative value is corrected by selecting the value of a compensating signal proportional to the product of the current value of the winding, rotational speed rotor and at least one fixed parameter selected. The system for the correction of the derivative of the rise time and fall time has a multiplier block (11), whose inputs are connected to a control and block (1), a block of constant parameters (12) and through a high-pass filter (10) with a current measuring resistor RP working motor, while the output of the multiplication block (11) is connected to the negative current derivative block (7) and through the inverter (13) with the positive current derivative block (6).
