“…Although the same desired trajectory is considered in this study, different trajectories can be realized easily by setting the synchronization factors appropriately. Of course, if feedforward compensators for the frictional and ripple forces, as discussed in Tan et al (2002) and Lee and Tomizuka (1996), are integrated into the proposed synchronization control system, then the synchronization performance might be further improved.…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms The new observer has only one scalar to be set, and thus can be easily incorporated into the control design to achieve precise output tracking. The convergence of the proposed estimator is compared with other three well-known schemes. Comparative simulation results show the satisfactory estimation and control performance.

“…Adaptive controllers may be designed to estimate both the magnitudes and phases of each of the Fourier series expansion components and achieve position tracking thanks to cogging compensation, see [6] and [7] for instance. Observer-based controllers can also be derived using an internal model by considering an extended system made up of the motor dynamics and the perturbations.…”

Abstract-This paper adresses the high precision positioning issue of permanent magnet (PM) linear motors, in presence of spatially periodic forces, also known as cogging. Using an internal model representation of this perturbation, an observerbased controller only relying on position measurements is derived. The observation error is not autonomous, and the stability analysis of the resulting closed loop system is regarded as the stability of two interconnected systems. For the motor to quickly track a desired trajectory, while being robust to large magnitude cogging forces, a small-gain like theorem is derived and used to tune the gains of the control law in an explicit way. The experimental results obtained through this method are then showed and compared with those of a PID controller.
