| Abstract |
Robust motion control requires accurate velocity
information. The authors have proposed “synchronousmeasurement
method (S method)” that measures the velocity
synchronous with alteration of pulse numbers. Accurate
velocity measurement is achieved in all speed ranges with
this method. The method, however, has several technical
issues for application in practice: accuracy often deteriorates
with nonideality of interpulse angles in optical encoders;
and disturbance observer needs modification to deal with
nonregular velocity measurement. This paper proposes some
solutions for the issues in S method. Experimental results
verify the validity of the solutions. |
