Mechanical Force Generator (MFG) is a planar and one degree of freedom mechanism that can provide any desired conservative force output that acts on its input links. One can reduce energy consumption of an actuator driving an existing machine by connecting an MFG (which provides any desired, optimum force variation) to a suitable link of the machine. In previous studies, determination of the optimum force variation has been investigated. In order to experimentally verify the performance improvement by coupling an MFG to a machine, a case study has been proposed. In this case study, a DC motor drives a symmetrical slider-crank mechanism at a constant angular speed. A conservative force is applied on the slider links of the mechanism and an MFG is designed to compensate for this conservative load on the motor. In this paper, the mechanical design and the electronic components of the experimental setup are explained. Finally, the controller performance and the power consumption of the actuator, with and without the application of the MFG, are discussed.

Implementation issues of real time position estimation for induction motors using rotor slot harmonics
Ertan, Hulusi Bülent; Keysan, Ozan (2013-11-15)
In this paper, an approach to identify rotor slot harmonics, from motor currents or from induced voltage in an internal or external search coil voltage is described. The importance of this method is that instantaneous value of the rotor slot harmonics can be determined in real time. In this manner, it is possible to determine motor speed or rotor position of a motor in a short enough time, for use in vector control. This method is independent of motor parameters. Using this method an additional feedback bec...
Investigation of parallel-connected GaN E-HEMT VSI-based servo drives
Yürük, Hüseyin; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-1-19)
Nonlinearities in voltage source inverters (VSIs) are thought to be the primary cause of output voltage distortions which cause low-order harmonics in the output current. These nonlinearities also considerably degrades control performance and system stability for low-speed applications with low-inductance motors, particularly when the system operates in the low-torque area. The impact of the nonlinearities on the phase current and current control of a silicon (Si) metal-oxide-semiconductor field-effect tran...
Investigation of multilevel inverters for d-statcom applications
Deniz, Mustafa; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009)
The most important advantages of Multilevel Inverters are the absence of a coupling transformer for medium voltage applications and low harmonic current content. In this way, relocatable and economical STATCOM systems can be realized. Complex control algorithms and the isolation problems of measurement devices and power supplies are the main challenging parts of this type of application. In this study, the design, realization, and the performance of a Voltage Source Type Cascaded Multilevel Converter Based ...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering
Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
STARTING TRANSIENTS IN SLIP ENERGY RECOVERY INDUCTION-MOTOR DRIVES .1. FORMULATION AND MODELING
AKPINAR, E; PILLAY, P; Ersak, Aydın (1992-03-01)
A detailed study of the rotor phenomena including the rectifier commutation angle and inverter harmonics is facilitated by the use of the actual rotor conduction sequence variables instead of transformed variables that are used in most other IM drive systems. The starting transients of slip energy recovery IM drives comprising three stages are presented here; (a) the starting from zero speed with a starting resistor connected to the output of the rotor rectifier; (b) a transition period in which the invert...
