7.1概述 功用:保证发动机正常工作的所需的“神经”系统组成:主要有滑油、起动、燃油与调节系统,以及保证它们正常运行的传动系统。有的机种还有喷水、冷却系统等。(为防内容重复,本章主要介绍滑油、传动系统) 7.2滑油系统

5.1燃烧室 (本节应注意与燃烧课程的协调,避免重复) 5.1.1概述 (1)功用:将燃的化学能转换成气体的热能并加热到涡轮前允许的温度。 (2)燃烧环境:

1.1基本类型 1.1.1活塞式+螺旋桨 汽油机等容循环(OTTO循环) 柴油机—等压循环(Disel循环) 做功特点: (1)进气量小 (2)各冲(过)程在同一汽缸内按序完成(个体作业”)→功率(生产率)受限

Handout 6: Proportional Compensation Eric Feron Feb25,2004 Plant under study: 1/10 G(s)=(s+1)(s/10+1)2 Compensation Scheme: We adjust the gain K in the feedback loop (draw the feedback loop below)

Handout 7: Lag and PI compensation Eric Feron Lag Compensation goals: Raise gain at low frequencies while leaving rossover &z higher frequencies untouched b≥0. When b=0: Add an integrator in the loop Typical lag Bode Plot
