Abstract
A feedback control system may include a feedback controller for controlling a plant using pulse density signals. The feedback controller may include a pulse density signal generator and a controller logic circuit. The pulse density signal generator may receive input command signals and generate signed or unsigned pulse density input signals. The controller logic may receive the pulse density input signals from the pulse density signal generator and feedback pulse density signals from the plant and may generate corresponding pulse density control signals for controlling the plant based on the input command signals. The controller logic may include a sign change logic, an addition circuit, and an optional amplifier circuit. The pulse density signal generator may also include rate transition circuits for ensuring that the pulse density input signals and the feedback pulse density signals are uncorrelated.
