This augmented edition of a respected text teaches the reader how to use linear quadratic Gaussian methods effectively for the design of control systems. It explores linear optimal control theory from an engineering viewpoint, with step-by-step explanations that show clearly how to make practical use of the material.The three-part treatment begins with the basic theory of the linear regulator/tracker for time-invariant and time-varying systems. The Hamilton-Jacobi equation is introduced using the Principle of Optimality, and the infinite-time problem is considered. The second part outlines the engineering properties of the regulator. Topics include degree of stability, phase and gain margin, tolerance of time delay, effect of nonlinearities, asymptotic properties, and various sensitivity problems. The third section explores state estimation and robust controller design using state-estimate feedback.
Numerous examples emphasize the issues related to consistent and accurate system design. Key topics include loop-recovery techniques, frequency shaping, and controller reduction, for both scalar and multivariable systems. Self-contained appendixes cover matrix theory, linear systems, the Pontryagin minimum principle, Lyapunov stability, and the Riccati equation. Newly added to this Dover edition is a complete solutions manual for the problems appearing at the conclusion of each section.

Trim & slimming
Size: 16 Short, Color: Deepest Dark
I was so pleased to receive these today. Their title says it all. So well made: the fabric is soft yet the weave is tight, the leg is just the right width at the bottom; and it's comfortably stretchy at the waist and leg. Deepest Dark seems like a true jeans color, blue yet somewhat navy. It's not bright so doesn't call attention to itself. Almost forgot -- the front pockets are just deep enough for a phone.

Slimming Look, Not Too Much Stretch
Size: 8, Color: Blue Format
Some stretch but not too much! I really like these. They hug and pull me in well. I’m slim through the hips with a bit of belly. I’m 5’5” 147.8 and these did not give me a muffin top even though I have a flabby belly. The color is exactly as described. They did not shrink after washing and the quality is what I expect as they are Lee jeans. They are very durable.

Button sucks!
Size: 14, Color: Deepest Dark
These are cute jeans and are great quality, especially for the price. I would've kept them, but had to return them because THE BUTTON IS AWFUL. It is SO hard to get through the hole. It's rounded on the edge so there's nothing to grab onto so it actually hurt my fingers to try to close them. I think the lack of stretch in the top was 25% the culprit, too. They were 100% my size and fit perfectly, so it's not a sizing issue. If I could make a recommendation to Lee it would be to rethink that horrible design and use just the regular button that all jeans come with.

Thighs waaay to big, otherwise literally perfect.
Size: 18, Color: Blue Format
One issue- the thighs were huge. Otherwise these jeans are perfect. They fit great everywhere else, quality material and good thickness. Waist is very comfortable. I wanted so badly to keep these but I knew I'd never wear them. I tried to get past the thigh issue, but they just looked silly.
