pid controller self-tuning system and method

摘要

"Pid controller self-tuning system and method" A system and method of use for self-tuning a pid controller used with an exciter and generator is disclosed. The system includes a power source, an exciter electrically connected to the power source, a generator that is electrically powered by the exciter, and a processor that provides a pid controller that calculates an estimated exciter time constant and an estimated generator time constant. with a least square of feature with forgetting the factor algorithm or using particle beam optimization (“pso”) to control the exciter field voltage. The least squared resource forgetting factor methodology includes using an estimated exciter time constant and an estimated generator time constant to calculate pid gains. pso includes increasing the voltage reference by a predetermined percentage over a predetermined period of time by initializing each particle position of the exciter time constant and the generator time constant, calculating the generator voltage, performing a suitability assessment and getting and updating the best values.
