| Abstract: | In this paper,a robust minimum-time control technique is presented for point-to-point motion of a linear positioning system with an ironless permanent magnet linear synchronous motor(ILPMLSM).For this system,a time-optimal control satisfying Pontryagin's minimum principle is in Bang-Bang fashion.A switching time computation algorithm using particle swarm optimization(PSO) is proposed to obtain bang-bang control law.Due to parameter variations and other disturbances,the obtained bang-bang control would resul... |
