摘要: A combined speed and direct thrust force control scheme in the synchronously rotating stator flux oriented reference frame based on sliding mode is proposed for a linear permanent magnet synchronous motor. First-order dynamics second-order nonlinear state-space model of as system states are presented machine. These dynamic models then utilized synthesis two laws regulation control. The produce orthogonal components command voltage which applied to machine by space vector pulsewidth modulated inverter. Importantly, integral action also directly included using modified first-order plus condition. eliminates steady-state error provides additional restoring effort tracking with Lyapunov stability analysis proves global asymptotic scheme. effectiveness method validated extensive experimentation prototype Practical results demonstrate excellent transient performance when compared state-of-the-art methods.
