Famous Quotes from the Book

"Optimal control is not just a mathematical abstraction; it is the key to unlocking efficient solutions for complex engineering systems."

"The ultimate goal of control theory is to find an ideal balance between system performance and resources expended—optimization is the bridge to achieve this."

"Estimation is as much an art as it is a science; understanding uncertainty is the first step in making confident decisions under noise and ambiguity."
