Abstract
In order to satisfy the requirement of angular acceleration measurement and solve the problem of direct detection
indirect measurement method is researched. As integration of angular acceleration is angular velocity
the latter is selected as signal source; Kalman filter is adopted to estimate angular acceleration. Experimental plat form is designed
step change of angular acceleration periodic change
and results indicate that the indirect measurement approach has good application value.
