Fuzzy logic based online adaptation of current and speed controllers for improved performance of IPMSM drive
(2013-02-12)
Precise torque and speed control of electric motors is a key issue in industries for variable speed drives (VSD). Over the years the induction motors have been widely utilized in industries for VSD applications. However, ...
Performance and emissions of a DI diesel engine fueled by different biodiesel blends
(2014-01-22)
Biodiesel has been a promising clean alternative fuel to fossil fuels, which reduces the emissions that are released by fossil fuels, and possibly reduces the energy crisis caused by the exhaustion of petroleum resources ...
Balance control of a five-DOF robot leg
(2015-06-15)
A biped robot, also known as a humanoid robot, is built to resemble the shape and perform
the actions of the human body. While functioning, a biped robot interacts with surrounding
human environments. Currently, various ...
Robust H infinity model reference tracking control of singular systems using T-S fuzzy model and LMI
(2014-12-12)
In this study, a Takagi-Sugeno fuzzy model based tracking controller is proposed for nonlinear
high index singular systems with a guaranteed H1 model reference tracking performance. A
coordinate transformation is introduced, ...
RBF neural network based generalized predictive control for nonlinear stochastic systems
(2014-01-22)
Almost all practical systems are nonlinear, which are subject to disturbances and contain uncertainties. In most cases, disturbances and uncertainties can be modeled as stochastic processes, which make it necessary to ...
Vibration control using switchable stiffness
(2015-01-13)
Over the last decade, the switchable stiffness (SS) control strategy has seen renewed
academic interest due to the need for effective vibration control techniques. The SS control
strategy involves switching the system’s ...
A nonlinear energy sink with energy harvester
(2014-12-11)
The transfer of energy between systems is a natural process, manifesting in many different ways. In engineering transferable energy can be considered wanted or un- wanted. Specifically in mechanical systems, energy transfer ...
Novel Hilbert Huang transform techniques for bearing fault detection
(2014-01-22)
Bearings are commonly used in rotary machinery; while up to half of machinery malfunctions could be related to bearing defects. A reliable bearing fault detection technique becomes vital to a wide array of industries to ...
Intelligent systems for active vibration control in flexible engineering structures / by Ji Xiaoxu.
(2008)
Vibration arises in almost all moving structures. Vibration control is important to many applications such as robotic arms, aircraft wings, buildings in wind, vehicle transmission systems,to name but a few. The objective ...
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 ...
