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...
Instability Mechanisms in Indirect Field Oriented Control Drives: Theory and Experimental Results
Analysis of saddle-node and Hopf bifurcations in IFOC drives due to errors in the estimate of the rotor time constant is presented. Experimental results showing such bifurcations are given and guidelines for drive commissioning are derived from these results.
متن کاملRobust Shaping Indirect Field Oriented Control for Induction Motor
Over the past years, thanks to the systematic use of digital microprocessors in industry, we have seen a very significant development in the regulation controls of the asynchronous machine. The latter is widely used in industry for its diversity of use and its ability to withstand great variations in its nominal regime. Currently, several types of control are proposed. Nonlinear controls such a...
متن کاملRobustness margins for indirect field-oriented control of induction motors
The influence of the rotor time constant mismatch on the stability of induction motors under indirect field-oriented control is analyzed. The results of [14] are generalized. A Lyapunov function which provides a global stability test and allows us to compute robustness margins is given. Different mechanisms for the loss of stability are detected by means of bifurcation analysis. Robustness marg...
متن کاملIndirect Field Oriented Control of Induction Motor Using Fuzzy Logic
This paper presents a fuzzy logic based speed control system for a current source PWM inverter fed indirect field oriented control of induction motors (IM). In this work the conventional PI controller is replaced by fuzzy based intelligent controller. The fuzzy logic controller employs different types of membership functions for each parameter for the efficient control of the drive system. The ...
