System and method for multi-channel control system

摘要

A system having has a pulse width modulation controller to successively activate each of a plurality of channels each in its own individual channel time slot is described. The system also has a sampling multiplexer configured to successively sample a signal derived from each of the plurality of channels during each individual channel time slot. Each individual time slot has an individual sampling sequence.

1. A multichannel control system comprising:
a pulse width modulation controller, wherein the pulse width modulation controller is configured to successively activate each of a plurality of channels, each channel of the plurality of channels having a non-overlapping individual channel time slot different from other channels of the plurality of channels, each individual channel time slot being a duration of time in which a corresponding channel is activated; and a sampling multiplexer configured to successively sample one after another a signal derived from each of the plurality of channels during each individual channel time slot, wherein all of the derived signals are individually sampled within each individual channel time slot, wherein each individual channel time slot comprises an individual sampling sequence having a sampling order, and wherein the sampling order of each individual channel time slot is different from each of the individual sampling sequences of channel time slots associated with the other channels of the plurality of channels.
