This paper presents a new development of an on-line hybrid self-tuning control algorithm of the Field Programmable Gate Array - Proportional Integral Derivative - Pulse Width Modulation (FPGA-PID-PWM) controller for DC-DC buck converter which is used in battery operation of mobile applications. The main goal in this work is to propose structure of the hybrid Bees-PSO tuning control al... https://www.roneverhart.com/Craggy-Range-Sauvignon-Blanc-Te-Muna-Road-Vineyard-Martinborough-2022/
