Abstract

In this chapter the concept of conventional direct thrust force control (conventional DTFC) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17] is rigorously analysed and experimentally evaluated for the linear PMSM. Linear PMSMs, especially those with low inductance and short pole pitch, exhibit significant ripple in flux and thrust force under conventional direct thrust force control. Aimed at reducing ripple in the flux and the force, various methods, including space vector modulation [18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28], model predictive control [29, 30, 31] and duty ratio control [32, 33, 34, 35, 36, 37, 38, 39] can be used.
