ME4232 - Syllabus

Course objectives :

Fluid power plays an important role in many sectors of the economy. It is used in aerospace, machine tools, off-road vehicles, material testing systems etc.

This course has three objectives:

• Introduce fluid power components, circuits, and systems

• Provide hands-on experience in designing, analyzing and implementing control systems for real and physical systems.

• Provide first hand experience in modeling, control and other dynamical systems concepts introduced in Systems Dynamics and Control (ME3281).

Throughout the course, students will be encouraged to derive and use mathematical models to make predictions and to answer queries.

Expected outcomes :

• Familiarity with common hydraulic components, their use, symbols, and mathematical models

• Ability to formulate and analyze simple mathematical models of hydraulic circuits

• Ability to identify single input single output (SISO) dynamical systems

• Ability to design, analyze and implement simple control systems

• Appreciation of advantages and disadvantages of various types of controllers

• Ability to relate control systems analysis with actual performance

• Intuitive and mathematical appreciation of dynamical system concepts (e.g. stability, instability, resonance)

• Appreciation of un-modeled real world effects

• Become very familiar with using Matlab for analysis and plotting.

• Comfortable with commercial hydraulic catalogs

Pre-requisite :

Thorough understanding of materials in ME 3281 or equivalent.

Texts :

Fluid power text :

"Eaton Industrial Hydraulics Manual" order it here

Systems & Dynamics texts :

K. Ogata, "Systems Dynamics", 3^rd Ed. Prentice Hall,

K. Ogata, "Modern Control Systems", 3^rd ed. Prentice Hall,

Close and Frederick , "Modeling and Analysis of Dynamic Systems".

Other texts:

"Industrial Hydraulic Technology", 2nd Ed. Parker Hannafin Training Module http://www.parker.com/training/

Merritt, "Hydraulic control systems", Wiley, 1967

Sullivan, "Fluid Power, theory and applications", 4th Ed. Prentice Hall, 1998

John S. Cundiff, "Fluid Power Circuits and Control", CRC Press, 2001.

The Parker book explains how things work without much analysis (similar to the Vickers text but not as colorful!). Merritt is an excellent (although old and expensive) book on modeling of hydraulics components and systems that is still being heavily used by researchers. Sullivan is written more in a regular text book style and discusses components, circuits and analysis.

Format:
