Sažetak
Actual units of Rotor voltage Frewuency Measurement(RFM)and Torgue Estimation (TE)are developed on the identical hardware base. The hardware structure of these units are digital signal processors DSP ADMC300, one DSP processor is employed for each unit, performing estimation algorithms on the separate circuits boards. The algorithms of estimated torque and speed are mathematically described in chapters 2.4 and 3.4. in this document. The communication program modules for torque (DAPCTO) and for speed (DAPCRF) are "connecting" the estimation torque and speed circuits boards, DATX130 and DATX132, with the rest of the main application of the crane controller program. This program is realized on the main board DAPC100, on the Motorola microcontroller MC 68332, using graphical user interface (GUI) environment, PCASE. The communication program modules has been realized in C code and packed in the graphical form as a single PC elements in the PCASE Library elements base. All needed parameters for element DAPCTO (DAPCRF) are coming from the application program parameters list. The actual (estimated) values of the torque and speed are transferred to the main board (to main application program) as any other I/O signal, using optical physical link
