A modified space-vector PWM method is studied so that the linearity of the inverter can be improved when modulation index M>1. Because constant V/F drivers for air-conditioner motors operate in a wide range output frequency, the synthesis of accurate output voltages has became an important issue. To resolve the problem, the well known instantaneous average voltage method is used for compensating for blanking time and input DC-link voltage ripple. The inverter is controlled by a M37705 single chip microprocessor and has been successfully used in A.C. compressor speed control of a home central air-conditioner system.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.

The U-type magnets are often used to generate the levitation force in the EMS system. This conventional electromagnet, however, can only control one degree-of-freedom. It cannot construct a levitation system solely by itself. A four-pole type yoke hybrid electromagnet is proposed instead of the usual U-type magnet and its magnetic levitation control is studied in this paper. The basic structure and characteristics of the proposed magnet are described first. Next the control system is designed. Luenberger observer, only using gap sensors, is applied to realize zero-power control. The semi-zero-power control with a disturbance observer is proposed to improve the performance, as well as the robustness, of the control system. The ideas of coordination with linear motor are discussed. Finally, the simulation results and corresponding experiments have been presented.","PeriodicalId":143007,"journal":{"name":"ICEMS'2001.
