The electrosurgical unit (ESU) is the most common device in modern surgery for cutting and coagulation of tissues. It produces high-frequency alternating current to prevent the stimulation of muscles and nerves. The commercial ESUs are generally expensive and their output power is uncontrolled. The main objective of the proposed study is to propose an economic ESU with an additional feature of output power regulation using a fuzzy logic controller (FLC) based proportional integral derivative (PID) tuned controller. Unlike the previous studies, the proposed controller is designed in a fully closed-loop control fashion to regulate the output power of the ESU to a fixed value under the consideration of highly dynamic tissue impedance. The performance of the proposed method is tested in the MATLAB/SIMULINK environment. In order to validate the superiority of the proposed method, a comparative analysis with a simple (PID) controller based ESU is presented.
电外科设备（ESU）是现代手术中用于切割和凝固组织的最常见设备。它产生高频交流电以防止刺激肌肉和神经。商用ESU通常价格昂贵且其输出功率不受控制。本研究的主要目的是提出一种经济的ESU，其具有使用基于模糊逻辑控制器（FLC）的比例积分微分（PID）调谐控制器来调节输出功率的附加功能。与先前的研究不同，所提出的控制器采用全闭环控制方式设计，以便在考虑高度动态的组织阻抗的情况下将ESU的输出功率调节到固定值。所提出方法的性能在MATLAB/SIMULINK环境中进行了测试。为了验证所提出方法的优越性，给出了与基于简单（PID）控制器的ESU的对比分析。
