SV-PWM Based Direct Thrust Force Control of a Linear Permanent Magnet Synchronous Motor

Part of the Power Systems book series (POWSYS)


In this chapter, two schemes for direct thrust force control (DTFC) based on space vector pulse width modulation (SV-PWM) are proposed, experimentally validated and compared for the prototype linear PMSM. The first direct thrust force control scheme is the PI controller-based regulation of the flux and thrust force and is referred to as “PI-DTFC”. The second direct thrust force control scheme is based on a linear quadratic regulator based control of the flux and thrust force and referred to as “Optimal-DTFC1”. It is important to note that Optimal-DTFC1 is based on a novel state space model which formulates the flux and thrust force dynamics for the linear PMSM.
