Many distributed energy (DE) resources are near load centers and equipped with power electronics converters to interface with the grid, therefore it is feasible for DE to provide ancillary services such as voltage regulation, nonactive power compensation, and power factor correction. A synchronous condenser and a microturbine with an inverter interface are implemented in parallel in a distribut...

This paper deals with Enhanced Phase Locked Loop Control scheme for Distributed Static Compensator (DSTATCOM) in the distribution system. The proposed control scheme based DSTATCOM eliminates current harmonics, maintains unity power factor at source, zero voltage regulation and load balancing. The Enhanced Phase Locked Loop (EPLL) Control scheme is based on Digital Signal Processing (DSP) which...

The objective of the research is to diminish unwanted forces generated by rotation and unbalanced rotor mass on the rotor of an electrical machine. These forces, dependent on rotational speed, cause vibration that, when occurring in the machine’s natural frequency, causes severe problems. Extra windings are built in the stator of the machine, and they are supplied with current to create an oppo...

The build-up dose in the megavoltage photon beams can be a limiting factor in intensity-modulated radiation therapy (IMRT) treatments. Excessive surface dose can cause patient discomfort and treatment interruptions, while underdosing may lead to tumor repopulation and local failure. Dose in the build-up region was investigated for IMRT delivery with solid brass compensator technique(compensator...

-This paper presents an algorithm for compensating delays that are distributed between the sensor(s), controller and actuator(s) within a control loop. This observer-based algorithm is specially suited to compensation of network-induced delays in integrated communication and control systems. The robustness of the algorithm relative to plant model uncertainties has been examined. 1. In troduct i...

This paper explains and demonstrates a model-following controller design based on the stabilized digital inverse system. Conventional digital inverse systems are constructed behind a plant to estimate unknown disturbances. Herein, the inverse system is designed in front of the plant. The model-following controller is then constructed on the basis of this structure. However, when the relative de...
