Lq-stochastic Control

emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

Stochastic LQ Control via Semide nite Programming

We study stochastic linear quadratic LQ optimal control problems over an in nite time horizon allowing the cost matrices to be inde nite We develop a systematic approach based on semide nite programming SDP A central issue is the stability of the feedback control and we show this can be e ectively examined through the complementary duality of the S DP Furthermore we establish several implicatio...

Power Is Nothing Without Control

Cardiac cell–based therapy, after a peak of untimely expectations of miraculous efficacy exceeding standard clinical practice, has faced the cardiological community and funding bodies with a predictable trough of disillusionment. In the light of more recent progresses, the field is by contrast moving toward a competitive differentiation phase, in which the resolution of the complex matching bet...

Robust frequency-shaped LQ control

Certain frequency-shaped standard linear quadratic (LQ) controllers involving state feedback have attractive loop robustness properties. These robustness properties may vanish in passing to an output feedback scheme, as when state estimates are used instead of states. The known exception to date is when the plants are minimum phase and state estimation with loop recovery is used, as in LQG/LTR ...
