1) clutch coupling self study: first, gear box control unit (14) controls direct-drive motor (1) and learns the maximum point of clutch coupling physical points and smallest point; Secondly, at the moment of torsion that the guidance panel input respective clutch of dSPACE hardware system (16) is transmitted, the Half engagement point of study clutch coupling;
2) clutch coupling self-adaptation: in the guidance panel input respective clutch service time of dSPACE hardware system (16), clutch abrasion coefficient is calculated in realistic model, the displacement signal that power and displacement sensing (5) gather, in conjunction with the Half engagement point of clutch abrasion coefficient auto modification clutch coupling, makes clutch coupling not affect its performance because of wearing and tearing;
3) emulate the separation of clutch coupling and joint: emulate when starting, gear box control unit (14) control imitation platform carries out self study and the self-adaptation of clutch coupling, after completing and non-fault time settling signal is passed to dSPACE hardware system (16);
DSPACE hardware system (16) carries out analog simulation according to the corresponding operating mode inputted in guidance panel;
When gear box control unit (14) receives the shift signal that dSPACE hardware system (16) sends, send clutch disengage command, direct-drive motor (1) accepts this clutch disengage command, namely drives worm and gear rack-and-pinion self-locking speed-down mechanism (3) to rotate;
The position signalling whether whether angular transducer (20) the Real-time Collection clutch coupling of worm and gear rack-and-pinion self-locking speed-down mechanism (3) be separated completely or engaged completely, feeds back to dSPACE hardware system (16) and judges;
Through judging; If be not separated completely, dSPACE hardware system (16) does not send any signal, and direct-drive motor (1) remains in operation until be separated completely; If be separated completely, send clutch separation settling signal, direct-drive motor (1) stops action; Meanwhile, realistic model carries out selecting gear shift, and after gear shift completes, dSPACE hardware system (16) sends the order that clutch coupling engages, and gear box control unit (14) sends engagement command to direct-drive motor (1); Gear box control unit (14) adopts fast, slow, fast engagement strategies according to actual condition; Through judging; If do not engage completely, dSPACE hardware system (16) does not send any signal, and direct-drive motor (1) remains in operation until engage completely, if be separated completely, send clutch coupling and engage settling signal, direct-drive motor (1) stops action;
Gear box control unit (14) sends loading command to DC load motor (13) while sending and engaging order, and heap(ed) capacity is calculated by dSPACE hardware system (16) and obtains;
Rotary speed torque sensor (9) Real-time Collection load heap(ed) capacity, feed back to dSPACE hardware system (16), realistic model carries out simulation calculation, judge whether heap(ed) capacity meets the demands, any signal is not sent when not meeting, DC load motor (13) continues to load, and sends direction signal and unload during overload; When meeting, sent order, DC load motor (13) stops loading; After loading completes, DC load motor (13) does not complete its work, the position residing for clutch coupling, load at any time, until clutch coupling engages completely, gear box control unit (14) sends to DC load motor (13) order that clutch coupling engaged, and emulation terminates.
