Online - - compensation device for feedback - positions of an encoder, and method for the operation of the same

摘要

Online - - compensation device for feedback - positions of an encoder, wherein the online - compensation - device on a motor is used, which is driven by a driver, in order to rotate with a constant speed, as a result of which the error of the feedback positions of the encoder are compensated, wherein the online - - compensation device:a compensation calculation quantity - - - unit comprising:a first processing unit, which a pre-treatment compensation - quantity and receives a pulse - increment the pre-treatment compensation - quantity and the pulse - increment to sum up; anda second processing unit, which is connected with the first computer unit and receives an encoder - pulse, in order to the encoder - pulse from the sum of the interface - compensation quantity and of the pulse - increment and thus an interval - - quantity compensation to produce;a position - - - interval evaluation unit, which, with the compensation quantity - - - calculation unit and the interval - - quantity compensation receives the positional - interval of the interval - - quantity compensation according to the resolution of the feedback - positions of the encoder to be evaluated; anda compensation modification quantity - - - unit, which, with the positions - interval - - evaluation unit, comprising:a third arithmetic unit, which has a first compensation - quantity, a second compensation - quantity and a weight value, about the first compensation - quantity and the second compensation - quantity to be multiplied with the weight value, in order in each case a first weight value - - compensation quantity and a second weight value - - quantity compensation to produce by weighting;a fourth processing unit, which the weight value and receives a value of 100%, in order to the weight value of the value of 100%, in order thus to generate an auxiliary - weight value;a fifth processing unit, which is connected with the fourth computing unit and the auxiliary - weight value and a feedback - - compensation quantity of a position - interval between the first compensation - quantity and the second compensation quantity - receives the feedback - - quantity compensation with the auxiliary - weight value to a feedback - - - quantity compensation weight value to generate;a sixth processing unit, which with the third processing unit and the fifth processing unit is connected and the first weight value - - compensation quantity, the second weight value - - compensation quantity and the feedback compensation quantity - - receives the first weight value - - compensation quantity and the ..
