為了滿足HIFU【1】【注】醫療系統要求，在分析常用水溫水位單一控制方式存在問題的基礎上提出了水溫水位智能控制系統。闡述了系統的硬件設計、控制方案及原理，并給出了水溫水位控制原理圖和部分軟件流程圖。仿真實驗結果表明, 采用該系統對水溫水位進行控制，取得了良好的效果，而且調節過程平穩。關鍵詞：水囊、傳感器、脈寬調制、比例/積分/微分控制器、智能控制

Aptitude control of medium water temperature and water level in HIFU medical treatment system XU Hui，LIU Feng Abstract: To satisfy HIFU medical treatment system request，an aptitude control system of medium is stated on the basis of analysis of conventional water temperature and water level single control mode and existing problems。The hardware design of system , control project and principle are described emphatically。Then the control principle chart of water temperature and water level，partial program flow chart are given。The emulational experiment result shows that the system adjusts placidly and receives well effect。
