This paper presents an experimentation with a vision based skill learning technique using Barrett WAM (a 7-DoF robot manipulator) and Microsoft's Kinect (a 3D sensor). This skill learning approach is based on Symbolic Encoding. Even though most of the imitation learning approaches focus on trajectory encoding, symbolic encoding offers a more concise representation of a skill which is easily transferable...
Multifunctional Grid Connected Inverters (MFGCIs) are playing a crucial role in improving the power quality in Micro grids. This paper focuses on the transient and steady state performance of a current controlled Multifunctional grid connected inverter to improve the grid current quality when connected to nonlinear loads. The multifunctional grid connected inverter incorporates active filter functionality...
Wind energy is the fastest growing renewable energy source. In wind power market Double Fed Induction Generator, is popular wind turbine system due to its reduced mechanical stress and high efficiency compared to others. But it is very sensitive to grid disturbances and can damage the power electronic converters connected to the machine due to over voltage and over current due to fault ride through...
This paper is focused on the design of the Fuzzy Sliding Mode Controller (Fuzzy SMC) for the Speed control of Permanent Magnet Synchronous Motors (PMSM) with Triangular and Gaussian fuzzy membership functions. PMSM are widely used in industrial applications such as robotic manipulators and machine tools due to its high efficiency, high torque to weight ratio and smaller size. One of the efficient...
This paper presents the design procedure of the sliding mode controller in cascaded structure for the output voltage regulation of dual input buck boost converter (DIBB) in continuous conduction mode. The design method is clearly illustrated for dual input buck boost converter with the above control strategy. The simulation results of DIBB for its responses to load and line regulations reveal the...
Recently semiconductor industry witnessed a revolutionary change with the development of wide band gap devices namely silicon carbide and gallium nitride. These devices are found to be superior to silicon because of their ability to be operated at high frequency, high temperature and high voltage with reduced switching losses. In this paper a comparison between Silicon and Silicon carbide semiconductor...
Spatial markers can be used to not only complete coordinate transformation between two or more different Cartesian coordinate systems, but also to provide the error evaluation of the above transformation. On the one hand, a group of transforming markers is responsible for accurate parameters i.e. rotation matrix and translation vector; on the other hand, a group of checking markers can be used to...
In this paper, a java-based simulator of dynamical systems and signals is presented. This simulator implements linear low-order process models. Stability analysis, open-loop control and closed-loop tests can be done with the application. Analysis of signals and noise is available using the Fast Fourier Transform (FFT). The main contribution is a Java application that can be used by the instructor...
This paper presents an innovative educational resource, based on a remote laboratory, which allows users to conduct real experiments through Internet in the area of electronics. A 3D virtual world has been created in which users, by means of their avatars, can interact with virtual replicas of instruments, circuit boards, components or cables and with peers and teachers, as they would in a traditional...
Influence of reasonable geometrical distribution of markers on motion parameters of rigid body is more significant than that of coordinate disturbance of markers. In this paper, a novel approach is proposed to determine a reasonable geometrical distribution of least markers for accurate motion parameters of rigid body. Firstly, geometrical distribution of marker attached to a rigid body is described...
