One-bit processing for real-time control

In conventional digital control an analogue signal is converted into multi-bit digital format with an analogue-to-digital (A/D) converter. A control law is implemented into some digital hardware architecture, resulting in a digital control signal after processing. This digital signal is reverted to analogue format by a digital-to-analogue (D/A) converter or converted to a series of high-frequency pulses by a pulse-width-modulation (PWM) logic, hence being able to drive a physical system. The A/D and D/A converters can be any precision according to the system requirement, e.g. 12-bit in many cases. This thesis, however, proposes one-bit processing for real-time control, which is a new concept in digital control. [Continues.]
