This paper presents a low-cost shaft position tracking control for a switched reluctance motor (SRM). For this low-cost implementation a discrete sliding mode angular position control was applied based on the reaching law control (RLC) approach. The SRM logic command and controller algorithm are installed in a low-cost system based on a digital signal controller (dsPIC). The system was designed in...
Despite becoming competitive with ac and dc machines, the necessity for a shaft position transducer makes switched reluctance (SR) machines lose their low cost advantage, mainly as low power machines such as fans and pumps. Many techniques have been proposed for indirect rotor position detection for SR machines. However, their characteristics can be summed up as being based on a lookup table plus...
Silicon-on-insulator technology utilizing very high resistivity handle wafers demonstrates sufficient performance for many cellular handset requirements. Technologies with either thin or thick device layers show promise. Thick-SOI prototype single pole six throw switch (SP6T) P-0.1dB of about 40 dBm and -75 dBc harmonic at 35 dBm output have been demonstrated at 900 MHz. Thin-SOI Ron-Coff product...
We describe a 0.18/0.5 um RF CMOS thick Silicon-On-Insulator (SOI) technology built on high resistivity (1 kOhm-cm) substrates. A high performance/high power RF MEMS contact switch can also be integrated in the technology through above-IC post-processing. This RFCMOS/MEMS integrated technology provides a platform for cost-effective monolithic integration of several RF RX/TX functions for next generation...
