In this paper the authors present an active control algorithm for position control of stepping servomotors with flexible transmission shaft. A non-linear mathematical model is derived to describe the dynamic behaviour of the system. To implement the full state-variable active-control technique, the non-linear model is first linearised. It is shown that the full state variables could be used in a closed-loop controller to introduce damping in the eigenvalues of the system. For realistic application of active control, a state estimator (observer) is used to construct the full state variables from a single measured signal. The estimated state variables are fed in the controller to generate the control signal.It is shown that this method facilitates the introduction of damping in all eigenvalues of the system and so eliminates the undesirable oscillation due to the flexibility of the transmission shaft. Furthermore the effectiveness of linear control algorithm on the non-linear system is studied. [ABSTRACT FROM PUBLISHER] |
