• An Efficient Adaptive Fuzzy Control Scheme for Industrial ManipulatorsAn Efficient Adaptive Fuzzy Control Scheme for Industrial Manipulators

    In this paper, a decentralized adaptive fuzzy control scheme for second order systems has developed. Simulation results for robot manipulator show that the proposed control scheme works well, even if the ideal model is not in concordance with the real inverse dynamics. An important feature of this study is that it has transferred the proposed...

  • A Review of Multilevel Inverter Topology and Control TechniquesA Review of Multilevel Inverter Topology and Control Techniques

    Multilevel inverters have matured from being a growing technology to a sound-established practical approached solution for low to medium voltage and high power application. The three major reported topology are cascaded H-bridge with separate DC source, neutral point clamp and flying capacitor. While in this paper a proposed cascaded H-bridge...

  • A Study on Efficient Transfer Learning for Reinforcement Learning Using Sparse CodingA Study on Efficient Transfer Learning for Reinforcement Learning Using Sparse Coding

    In this study, we have proposed a novel technique to employ sparse coding in transfer learning for reinforcement learning. By applying the knowledge to the bases of sparse coding dictionary matrix, we succeeded to choose the correct knowledge that should be transferred to new environment target tasks. We experimented the proposed method on th...

  • Environmental Control of a Greenhouse System Using NI Embedded Systems TechnologyEnvironmental Control of a Greenhouse System Using NI Embedded Systems Technology

    We have presented the application of an automated greenhouse system using NI Embedded Systems Technology. The system is instrumented with sensors and actuators and controlled by an embedded cascaded PID algorithm in order to provide accurate control of the air temperature within the greenhouse. A simulation model of a subsystem has also been ...

  • Control of Quadrotor Unmanned Aerial Vehicles Using Exact Linearization Technique with the Static State FeedbackControl of Quadrotor Unmanned Aerial Vehicles Using Exact Linearization Technique with the Static State Feedback

    It is known that the q-UAV system is 4-input 4-output Affine nonlinear system of degree 12 and that it can not be exact linearizable by the static state feedback. So, to apply this control technique, it is necessary to augment the total system of the q-UAV by introducing two integrators. In this paper, we suppose that the vertical position is...

  • A Redundancy and Operation of Power Control System for a Deep-Space Small ProbeA Redundancy and Operation of Power Control System for a Deep-Space Small Probe

    The Shinen2 was launched in December, 2014 and had three types of communication lines: a Communication line (C-line), an Amateur Radio Relay Experiments line (A-line) and a Beacon line (B-line). The A-line and Cline were used for the specific communication modulus, WSJT, which was able to communicate with the low power transmitter in space. T...

    The algebraic approach to term-domains of linguistic variables is quite different from the fuzzy sets one in the representation of the meaning of linguistic terms and the methodology of solving the fuzzy multiple conditional reasoning problems. It allows linearly establishing the Quantifying Semantic Curve through the points corresponding to the ...
