Abstract
In this chapter, a combined sliding mode adaptive observer for flux and speed estimation of the direct thrust controlled, surface-mount linear PMSM without using position sensors is proposed. The observer comprises a linear state observer combined with a modified nonlinear sliding mode component. The sliding mode component is improved by using two boundary layers which reduces the chattering without compromising robustness.
