Control system of the multiimpellent asynchronous electric drive of a direct-flow drawing camp
The system of synchronisation of speeds of drawing drums in the asynchronous electric drive of a direct-flow camp under the scheme the frequency converter - the asynchronous engine with feedback on speed for the purpose of stabilisation of sizes holdback tension a wire between drums is considered. The program for the decision of the differential equations of dynamics of mathematical model of a direct-flow drawing camp is offered at research of quality of transients of technological parametres. Results of researches of the developed control system by the camp electric drive on computer model in the environment of program complex MatLab which confirm working capacity of the offered control system with the electric drive are resulted. Thus received qualities of regulation quite meets requirements of technological process as errors of maintenance of speed of drawing and holdback tension in all operating modes of a camp do not exceed as much as possible admissible values and make accordingly no more than 0,3 м/c and 4 %.
