Abstract:
Disclosed embodiments utilize MIP techniques to determine optimum bit sequences that minimize PWM artifacts. The problem would first be restructured and redefined into a form suitable for MIP. An objective function designed to minimize PWM artifacts would allow for evaluation of resulting bit sequences in order to determine optimality. Constraints (that relate the inputs and variables) are developed. These constraints would determine whether a particular bit sequence can be used on a given system, and whether a particular bit sequence would satisfy any user defined rules. Once these are determined, an MIP solver would generate an optimized bit sequence(s). Only bit sequences that satisfy the constraints would be evaluated using the objective function, allowing for a quicker determination of a solution. This MIP solution may be generated quickly, allowing for a shorter production period while still optimizing the bit sequences to minimize PWM artifacts.
