Abstract
The direct thrust force control (DTFC) scheme of permanent magnet synchronous linear motor (PMSLM) is mainly inspired by the direct torque control (DTC) of its rotating counterparts, to achieving excellent force characteristics. However, due to the inherent characteristics of PMSLM, such as large air gap, small equivalent inductance, and large mechanical time constant, the control performance of the traditional DTC algorithm is greatly deteriorated, which are of prime concern. In this paper, the traditional DTC of PMSLM is analyzed strictly, with the limitations pointed out. Contributed to the concept of predictive control, by optimizing of switching vector, a new algorithm named model predictive-direct thrust force control (MP-DTFC) is proposed. With the introduction of a disturbance observer, the thrust performance of MP-DTFC is improved. At the same time, the switching frequency is optimized, thrust and flux ripple is suppressed, and outer loop control performance is improved, when compared to the state of the art.
