一种基于模糊PID的高压高精度四象限电源的设计
Design of a High-voltage and High-precision Four-quadrant Power Supply Based on Fuzzy PID
摘要
Abstract
When conducting scientific research on instrumentation,a stable and well-performing power supply often makes the experiment achieve twice the result with half the effort.At present,the domestic market has a large demand for high-precision four-quadrant power supply.Based on this background,a high-voltage and high-precision four-quadrant power supply based on fuzzy PID is designed.In this paper,the method of combining hardware closed-loop with software closed-loop is adopted,which greatly improves the effectiveness of the measurement results.The software control loop uses 24-bit ADC chip ADS12xx and 24-bit DAC chip PCM17xx.The hardware closed-loop is realized by building a hardware PID circuit.Through experimental tests,the output voltage meets expectations,and it is continuously adjustable in the four gears of medium voltage and high voltage,and the voltage ripple is below 0.4 V.关键词
