Based on Direct Thrust Control for Linear Synchronous Motor Systems

The direct thrust control (DTC) has been utilized as a general formalism methodology for permanent-magnet linear synchronous motors (PMLSMs). The imposition control policies did not seem to handle the inherent flux linkage problems. This paper will try to propose a solution for the problems. This paper presents a genetic PI parameters generator and a new DTC policy for the motor control systems. Moreover, this paper also proposes a new switching table which can assist in selecting the optimum voltage vectors for the control system. The advantage of the proposed approach is that the clear presentation of the system behavior and readiness for implementation. Finally, some results of the simulation and the experiment both are met as expected. To the authors´ knowledge, this is the first work that employs DTC to implement on a real-world PMLSM which is starting at arbitrary positions and can be allowed moving in the full route.
