Alinearized transient-state mathematiacl model is derived using the phasor method andthe electromagnetic dynamics. Three independent, constant-frequency PWM current control loops are developed. Several experiment are descrided which were performedto verify the linearized model, thus obtaining a nominal transfer function for theSLIM. Three control approaches, such as conventional PID control, optimal PID controland H-Infinity control, are used to track the reference velocity command during startupas rapidly as possible while avoiding large overshoots and rejecting the effects of load variation. After developing high-performance current and velocity control loops,two types of position controllers are designed to complete the positioning task withoutexceeding the maximum velocity of the SLIM. The experimental setup is composed of aprecisely laser displacement measurement unit, a ramp comparison PWM current inverter, a host computer PC-486 and a digital signal processor (DSP) TMS320C31 with 16-bitanalog-to-digital converters and digital input/output circuits. Computer simulationsare described which were performed to illustrate effectiveness and feasibility of theproposed control laws. Experimental results show that the proposed linearized modelis valid and the proposed methods are capable of giving excellent results on the SLIM.
