Reference excerpt

Homâyun Serâji (Persian: همایون سراجی 1947 – 16 April 2007) was an Iranian scientist, engineer, a JPL senior researcher and former professor at Sharif University of Technology who published extensively in the field of multivariable control systems, focusing on optimal control, pole placement, multivariable PID controllers, and output regulation. Also he has significant publications in the field of Robotics, and space exploration.

Education Seraji was born and grew up in Tehran. He ranked first in the Iranian national high-school diploma examinations in 1965. He then moved to the United Kingdom and studied at Sussex University and majored in Electrical Engineering. Seraji earned his Ph.D. in Control Systems at the University of Cambridge in 1972.

Career In 1974, he joined Aryamehr University of Technology (now Sharif University of Technology), as a Professor of Electrical Engineering and was involved in teaching and research in control systems for ten years. He was also selected as a United Nations Distinguished Scientist in 1984. In 1985, Seraji joined NASA's Jet Propulsion Laboratory (JPL) and Caltech. During his tenure at JPL, he conducted extensive research that has led to major contributions in the field of robot control systems, particularly in: adaptive robot control, control of dexterous robots, contact control, real-time collision avoidance, rule-based robot navigation, and safe spacecraft landing. The outcome of his research in controls and robotics has been published in 98 peer-reviewed journal papers, 119 refereed conference publications, 5 contributed chapters, and has led to 10 patents. In 2003, he was recognized as the most-published author in the 20-year history of the Journal of Robotic Systems.

Worked examples

Example 1 — a first encounter with Homayoun Seraji

Start with the simplest possible case. Write down what Homayoun Seraji claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Homayoun Seraji before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Homayoun Seraji ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Homayoun Seraji

In research: Homayoun Seraji appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Homayoun Seraji in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Homayoun Seraji is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 2007 deaths, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Homayoun Seraji outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
