Speed Observer Design for Linear Induction Motor Drives
In this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (LIMs). Dynamical equations of LIM have been considered accurate. In other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. Then equations of the reference model and adaptive mode...
متن کاملHigh-Speed and Low-Power Flash ADCs Encoder
This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...
متن کاملEstimation of Motor Startup Speed Profile Using Low-Resolution Timing Signals and Motor Speed-Torque Curve
Motor startup speed profile of motor rotational speed versus rotational angle can often be very useful during product developments, such as for detailed kinematic or dynamic component analyses. In compressor tests, a sensor, usually a proximity probe or an optical pickup, is commonly used to generate low-resolution timing signals. The lowresolution timing signals are sufficient to detect the an...

متن کاملNonlinear speed observer for high-performance induction motor control
In this paper, we consider tbe problem of estimah ing the angular velocity of an induction motor using encoder measurements. -0 methods are compared, In tbe first method, tbe speed is found by calculating the backward differes~ce of tbe position measurem ent and low-pass filtering the result. In the second method, the velocity is estimated using a nonlinear observer constructed using the known ...
