Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In this proposed FO-PLL, method, a regulable fractional order r is involved, which means that the FO-PLL provides an extra degree of freedom. In fact, the conventional phase-locked loop (PLL) applied in sensorless PMSM control can be seen as a special case of the proposed FO-PLL. By selecting a proper fractional order r a better performance may be achieved. The computer simulation results demonstrate the effectiveness of the proposed method.Key words: fractional calculus; fractional order phase-locked loop; sensorless control; sliding mode observer; permanent magnet synchronous motor; speed controll

A six people s rushing replies an implement, use some s switches in toggle switch K0 ~ K5 is that ON accomplishes when rushing to reply button , nobody rush to answer, 6 numerical code circulation takes turns at demonstrating 1 ~ 6 (horse races) , who rushes to reply the numerical code stops having a ride on a horse , first, whose serial number, has simultaneous light of 6 numerical codes again afterwards the key presses down. System denies responding to, until this place is OFF batch , the wheel restoring 1 ~ 6 horse races starting time as soon as rushes to answer.

This program demonstrates operation of ADC0 in polled mode. The ADC0 is // configured to use writes to AD0BUSY as its start of conversion source and // to measure the output of the on-chip temperature sensor. The temperature // sensor output is converted to degrees Celsius and is transmitted out UART0
