Abstract: PROBLEM TO BE SOLVED: To provide a signal conditioning circuit that time share multiplexes antialiasing filters and an A/D converter.
SOLUTION: A plurality of first tier multiplexers each time share multiplex one of the plurality of antialiasing filters between a plurality of AC or baseband input signals. A second tier multiplexer selects its inputs from the outputs of the first tier multiplexers. The output of the second tier multiplexer feeds the high speed A/D converter, which is thus time share multiplexed. In this manner, a plurality of sensors can share a single A/D converter. After allowing a settling time for the multiplexers and antialiasing filters, a plurality of samples of the input signals are taken, such as for one period. The samples of each AC input signal are multiplied by a sine vector and a cosine vector. The product vectors are then each averaged and the root mean square of the two averages yields the magnitude of the input signal. Mechanical angle of the input signal can be determined based upon the sign of the sine and cosine product vector averages.

Abstract: PROBLEM TO BE SOLVED: To provide a signal conditioning circuit that performs time division multiplexing of anti-aliasing filters and A/D converter. SOLUTION: A plurality of first tier multiplexers performs time division multiplexing via one of a plurality of anti-aliasing filters between a plurality of AC or baseband input signals from a plurality of sensors. A second tier multiplexer selects its inputs from the outputs of the first tier multiplexers. The output of the second tier multiplexer is supplied to a high-speed A/D converter. Thus, the A/D converter is subjected to time division multiplexing by the second tier multiplexer. In this manner, a plurality of sensors can share a single A/D converter. After allowing a settling time for the multiplexers and anti-aliasing filters, a plurality of samples of the input signals are taken for one period, for example. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: A system for controlling an electric motor includes a controller and a position indicator that provides position information regarding at least one motor component to the controller. The controller utilizes phase relationships indicative of the position information to determine the actual position of the component of interest. The phase information in one example is derived from the output of a resolver that provides two output signals corresponding to sin (theta) and cos (theta), where theta is the angular position. Utilizing the phase relationship simplifies the task of determining accurate position information that is useful to modify motor control signals to compensate for latency when making position determinations, velocity calculations or both. The inventive system makes it possible to use less expensive electronics to arrive at more reliable results.
