Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment: the control system that a kind of flat-knitting machine head as shown in Figure 1 commutates at a high speed, this control system comprises host computer, servo-driver, for the servomotor that drives flat-knitting machine head to walk and the sensing device detecting head actual motion speed, wherein host computer comprises as lower module:
-the first control module;
-for calculating the computing module of acceleration-deceleration curve; And
-for setting the setting module of the flat-knitting machine head speed of service.
Described servo-driver comprises
-the second control module; With
-for comparing the comparison module of head actual motion speed and the setting speed of service.
Sensing device signal connects host computer, and host computer signal connects servo-driver, and servo-driver connects the servomotor for driving flat-knitting machine head to walk by the second control module in it.
Computing module signal in host computer connects setting module, for rational acceleration-deceleration opisometer is calculated, and given setting module, keep reasonably commutation speed of service curve to control flat-knitting machine head; The signal output part of the setting module in host computer and sensing device signal output part connect the comparison module in servo-driver respectively, for actual motion speed and the setting speed of service being compared, export the first control module that fiducial value feeds back to host computer.Host computer controls servo-driver by the first control module, thus drives the servomotor for driving flat-knitting machine head to walk.Here sensing device connects comparison module preferably by host computer signal, the speed of service information of reality can be retained in host computer like this.But consider from alleviating host computer burden, above-mentioned sensing device also can connect comparison module by direct signal.
