  1. 21. Implement vibration test control system, in MATLAB for National Instrument equipment

    University essay from Institutionen för teknik, TEK

    Author : Fatemeh Fakharian; Ali Nafisi; [2011]
    Keywords : MATLAB; Data Acquisition Toolbox; Modal test; National Instrument; closed loop controlling;

    Abstract : Finding non-linearity is a common application of modal testing but in this way, there is a need to control the input signal. Nowadays, commercial data acquisition software is not enough flexible in controlling the applied signals, whereas MATLAB as general software which supports National Instrument makes it possible to run modal test and control input signal via closed-loop controlling.

  3. 22. Simulations of Rotating Brushless AC Excitation System with Controlled Thyristor Bridge Rectifier for Hydropower Generators

    University essay from

    Author : Peter Butros; [2011]
    Keywords : hydropower; generator; exciter; thyristor; vattenkraft; generator; matare; tyristor;

    Abstract : This thesis aims to simulate and find out more about the electrical dynamics of a six-phase exciter for hydropower generators. Because ordinary electric circuit-based simulation software only simulate three-phase electrical systems, a FEM-based software is used for the electrical dynamics simulations of the six-phase system.

  5. 24. Model Based Parameter Estimation for a Missile

    University essay from KTH/Reglerteknik

    Author : Per Hägg; [2009]
    Keywords : ;

    Abstract : Traditionally direct integration of the measurements from an IMU (inertial measuring unit), measuring the acceleration and inertial angular velocity of the missile, is used to determine a missiles position and state. However, if some prior information about the missile dynamics is known, this method should be suboptimal. READ MORE

  6. 25. Computational Modeling of Deep Brain Stimulation

    University essay from Institutionen för medicinsk teknik

    Author : Marcus Petersson; [2007]
    Keywords : Deep; Brain; Stimulation; DBS; neural; response; pulse; biphasic;

    Abstract : Deep brain stimulation (DBS) is a surgical treatment technique, which involves application of electrical pulses via electrodes inserted into the brain. Neurons, typically located in the basal ganglia network, are stimulated by the electrical field. READ MORE
