Analysis of improvement for turn on/off performance of the MOSFET gate drive waveform
(2012-11-10)This thesis shows that the gate waveform of a power MOSFET driven by a specialized driver chip used in industry is imperfect and induces increased power loss in the MOSFET and lowers overall efficiency. The accurate ... -
Control of doubly fed induction generator based wind energy conversion system
(2014-01-22)The doubly fed induction generator (DFIG) is widely used in today’s wind energy conversion industry. The DFIG is essentially a wound rotor induction generator in which the rotor circuit can be controlled by external devices ... -
Control of flexible-link manipulator
(1998)Flexible-Iink manipulator has many advantages over classic rigid body manipulator in industrial and space applications. However, it also poses high requirements on controller design, to ensure the accurate tip position ... -
The Correlations and the power characteristics of special classes of binary sequences for multicarrier communications
(2009)In recent years, multicarrier communication has attracted considerable attention as a promising technology that enables transmission of high data rates. One of major drawbacks of multicarrier communications is the high ... -
Efficiency optimal control of interior permanent magnet synchronous motor / by Fasil Abera.
(2009)There has been a growing concern over energy consumption since the past decade mainly because of the soaring cost of energy and tight environmental laws and regulations. In this thesis a model based efficiency optimization ... -
Frequency domain tuning approach for adaptive feedforward controllers
(2003)Feedforward control provides a means for compensating measurable disturbances before the process output is affected. A novel tuning strategy for tuning feedforward controllers in frequency domain is developed in this ... -
Frequency response based system identification and controller tuning
(1997)A detailed simulation based analysis of different frequency response and transfer function identification techniques are performed and critically studied. Standard closed loop and open loop recursive least squares system ... -
Governor control for Kakabeka Falls Generating Station
(1999)This thesis examines a specific problem of governor control on a set of hydroelectric turbines that suffer from severe wicket gate leakage. Linear modeling and the steady state behavior of each turbine is investigated ... -
Investigation into the use of ELG for stand alone power system frequency control
(2006)The use of ELG for stand alone power system frequency control is investigated in this thesis. Characteristics of a stand alone power system with PCR-ELG are presented. Dynamic simulation of the system is developed using ... -
Iterative learning control for robot manipulators
(2004)When a system is performing the same task repeatedly it is, from an engineering perspective, advantageous to use the knowledge from the previous iterations of the same task in order to reduce the error on successive ... -
Model reference adaptive control system using frequency domain performance specifications
(1999)MRAS (Model Reference Adaptive System) to achieve frequency domain performance specifications with different transfer function identification techniques are experimentally studied. Standard open loop and closed loop ... -
Modeling and analysis of limit cycles in buck converters under PI control
(2005)A zero order hold equivalent discrete-time model of the buck converter for computing its large signal frequency-response is developed and experimentally verified. It is shown that with a dc bias and a sinusoidal variation ... -
Modeling and control of a flexible-link manipulator
(2001)The behaviour of a flexible-link robotic manipulator is studied using an experimental apparatus. The system is modeled based on the physical laws governing system dynamics. A non-linear rigid body model is developed which ... -
Modeling of PWM boost converters for continuous and discontinuous inductor current modes
(2006)Owing to the relatively more complicated nature of the boost converter with non-ideal elements and operating in continuous and discontinuous inductor current modes, a parsimonious large signal and small signal model for ... -
On-line estimation of first order plus dead time process parameters based on under or over-parameterized models
(2007)Simple on-line process identification methods that can be used in tuning PID controllers or any other controllers have been studied in this work. The underlying continuous-time first order plus dead time FOPDT process model ... -
Optimal trajectory control of series resonant converter
(2001)Resonant power converters have gained increased attention in industry due to various advantages over conventional pulse width modulation (PWM) converters. Resonant converters have improved transient response, reduced ... -
Robust control of DC-DC boost converter / by Hisham Mahmood.
(2008)In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller ... -
Technical feasibility and economical viability of remote hybrid power systems in Northern Ontario
(2011)As of 1996 there were 302 remote communities with a total population of 205,041 in Canada. These communities are not connected to the Bulk Electric System (BES) and as such are responsible for maintaining their own power ... -
Time-domain steady-state analysis of circuits with multiple adaptive grids
(2005)An effective adaptive algorithm to calculate the steady-state response of circuits is developed. This algorithm offers a powerful alternative to traditional steady-state simulation techniques, such as the shooting method ...
