δ 課程大概內容
Control is the action of causing a system variable to approach some
desired value. It is also a fundamental and universal problem-solving
approach in many traditional and interdisciplinary fields.
A control system, in a very general sense, is a system with an
(reference) input that can be applied per the desired value and an
output from which how well the system variable matches to the desired
value (e.g., errors) can be determined. It can be found in daily life,
almost all engineering disciplines, and even biological and social
studies. For examples, bicycle riding involves a control system
comprising of a bicycle and a rider, with inputs and outputs
associated with the desired attitude, speed, and direction of the
bicycle. Temperature control systems have applications in household,
automobile, aerospace, office, factory, and agriculture environments.
Motion control systems are critical to factory automation and
precision instruments, such as industrial robots, atomic-force
microscopes, and step-and-scan photolithography exposure systems.
Many modern cameras equip with autofocus and vibration compensation
systems to minimize image blur. Many kinds of circuits such as phase
lock loops, operational amplifiers, and voltage regulators rely on
control to ensure their functions and performance. A living body is
a complex control system where many critical variables such as
heartbeat rate, blood pressure, and body temperature are regulated
constantly for health. Central banks of most countries around the
world set interest rates as a way to control inflation.
This undergraduate course is designed for junior and senior
(3rd/4th yr.) students to apprehend basic modeling, simulation,
analysis, and design techniques for control systems. It intends to
cover the fundamentals of “classical control” that primarily
focuses on frequency domain feedback control approaches for
single-input-single-output systems. When time permits, some essential
elements in modern-day control engineering such as state-space
techniques will be covered.

Ω 私心推薦指數(以五分計)
綜合: ★★★★ (原因下述)
想入門控制: ★★★★★
不想寫作業: ★★★★★
只要學分: ★★★★★
η 上課用書(影印講義或是指定教科書)
自製投影片
μ 上課方式(投影片、團體討論、老師教學風格)
投影片為主,板書、matlab、實體玩具demo為輔
老師上課很喜歡嘴砲,口條清晰思路清奇
喜歡問大家問題,回答都直接加期中/期末/學期成績
我光學期加分就加了6分,直接混到A+
另外教授上課會介紹好用的 MATLAB 功能,
也把一些經典手動大爆算的技巧(像Mason's gain formula)拿掉了,
所以想要跟 MATLAB 比賽計算能力的可以修其他教授的或左轉機械系(X
教授講的時候很注重理解,
所以每個技巧為什麼有用跟要解決什麼問題都很清楚,
在修的時候真的有種一步步建構出一套有系統的理論的感覺
(雖然現在都忘光了)
很推薦想入門的人來修(不過準備考研好像還是要學會大爆算
σ 評分方式(給分甜嗎?是紮實分?)
Midterm Exam: 30%
Final Exam: 40%
Final Project: 30%
特殊規定:
→ 考試都有出席、project有繳交(白卷也可)學期成績保底60
→ final project 做前三好的無視考試成績直接A+
除了上課發言的分數跟用送的差不多外,其他算扎實分。
ρ 考題型式、作業方式
考題有選擇(須說明原因)、計算、證明、畫圖。
考2節課,共6題(沒記錯的話期中期末都是)
Final Project 是用 MATLAB 模擬一個2D的登月器著陸,
並利用上面的 Active Momentum Exchange Impact Damper 讓著陸不會傾倒。
光看懂整個 project 和提供的 MATLAB code 就燒上不少時間,
最好提早開始。
ω 其它(是否注重出席率?如果為外系選修,需先有什麼基礎較好嗎?老師個性?
加簽習慣?嚴禁遲到等…)
不點名,考試有到就好。
因為會用一些 Laplace 之類的,修過電路學、微方、信號之類的可能比較好(?)
不過考試都會給表可以查所以也不用很熟,知道在幹嘛就好
最後來提一下綜合評價 -1★ 的原因:(感覺不提會被其他有修課的嗆)
原先 Final Project 的死線剛好壓在期末考週的週五中午,
但因為提早很多公佈題目,所以理論上可以事先安排好,
就我所知也沒有人對死線提出意見。
但理所當然的秉持著電機的精神(X),
八成的人都是到期末考週邊讀書邊擠時間出來趕完 project。
然而,就在死線過後約 2.5 小時,教授寄信說因為有同學記錯死線,
直接延長兩天半,並增加兩天的緩衝(扣5分)
於是犧牲睡眠跟讀其他科的時間熬夜趕出 project 的人們就暴動了
後續雖然好像有把在原本死線之後才交的另外扣分,
但整體處置仍稍嫌粗糙,所以姑且扣一星,供大家參考。
Ψ 總結
除了特殊事件有點雷以外很推,
學了很多酷酷的技巧 \root locus大法好/

我認識有修的對這門的感受全是幹意滿點

我有做好被怒噓的心理準備了
