摘要
本文介绍了一种模拟集成分数阶 2 型模糊 PID 控制系统。目前的方法通常依赖于高能耗的嵌入式数字系统,能耗水平从几微瓦到几毫瓦不等。为解决这一局限性,我们提出了一种全模拟设计方案,让人们深入了解模拟电路在复杂和不确定环境下实现高能效稳健控制的潜力。它由高斯函数、最小/最大、运算跨导放大器电路和用于实现分数阶组件的电阻电容网络组成。该控制器可在电压较低的电源(0.6 V)下运行,功耗极低(861.8 nW),有利于不间断地长期运行。布局后仿真结果证实了拟议设计的正常运行。该系统采用 Cadence IC Suite 在台积电 90 纳米 CMOS 工艺中进行设计和仿真。
A Low Power Analog Integrated Fractional Order Type-2 Fuzzy PID Controller
This paper introduces an analog integrated fractional order type-2 fuzzy PID control system. Current approaches frequently depend on energy-intensive embedded digital systems, consuming substantial energy levels ranging from a few μW to mW. To address this limitation we propose a fully analog design offering insights into the potential of analog circuits for powerefficient robust control in complex and uncertain environments. It consists of Gaussian function, min/max, Operational transcoductance amplifier circuits and Resistor-Capacitor networks for the implementation of the fractional-order components. Crafted for operation under a reduced voltage supply (0.6 V), the controller attains minimal power usage (861.8 nW), facilitating uninterrupted, extended-term functioning. Post-layout simulation results confirm the proper operation of the proposed design. The proposed system is designed and simulated using the Cadence IC Suite in a TSMC 90 nm CMOS process.
