This paper presents a novel control algorithm for a modular high-frequency converter. This control algorithm is designed to achieve an effective frequency higher than the switching frequency on the passive elements. As a result, the ripple on the output is suppressed, and smaller capacitors can be used. In this work, the modular high-frequency converter is modeled by equivalent boost converters. Based on the equivalent models a control algorithm is developed. The accuracy of the algorithm has been verified by simulation results using PLECS in the MATLAB/Simulink environment.

This paper discusses the modeling and control of a robotic manipulator with a new deburring tool, which integrates two pneumatic actuators to take advantage of a double cutting action. A coordination control method is developed by decomposing the robotic deburring system into two subsystems; the arm and the deburring tool. A decentralized control approach is pursued, in which suitable controllers were designed for the two subsystems in the coordination scheme. In simulation, three different tool configurations are considered: rigid, single pneumatic and integrated pneumatic tools. A comparative study is performed to investigate the deburring performance of the deburring arm with the different tools. Simulation results show that the developed robotic deburring system significantly improves the accuracy of the deburring operation.

Intensive utilization of Induction Heating (IH) innovations can be seen in numerous areas such as manufacturing industries, domestic or house hold and medicinal applications. The development of high switching frequency switches has encouraged the structure of high frequency inverters which are the key component of IH technology. Controlling the power output in a high frequency inverter for IH application is relatively complicated. This paper focuses on designing and developing a typical series resonance inverter and control it by FPGA-based controller. A MOSFET switch-based DC to AC converter is designed and Zero Voltage Switching (ZVS)-based switching strategy is accomplished to acquire less stress on switching devices and greater conversion efficiency. In this technique, secondary switched capacitor cell was proposed for resonant inverter of high frequency. To optimize the performance of the proposed inverter, the FPGA-based control system is implemented. Higher power density is the greatest advantage of this topology. The experimental and simulation model of the proposed series resonant inverter (SRI) for heating applications is developed and simulated using MATLAB/Simulink software.

Theory and simulation results have demonstrated that four, variable speed flywheels could potentially provide the energy storage and attitude control functions of existing batteries and control moment gyros on a satellite. Past modeling and control algorithms were based on the assumption of rigidity in the flywheel’s bearings and the satellite structure. This paper provides simulation results and theory, which eliminates this assumption utilizing control algorithms for active vibration control (AVC), flywheel shaft levitation, and integrated power transfer and attitude control (IPAC), that are effective even with low stiffness active magnetic bearings (AMBs) and flexible satellite appendages. The flywheel AVC and levitation tasks are provided by a multiple input–multiple output control law that enhances stability by reducing the dependence of the forward and backward gyroscopic poles with changes in flywheel speed. The control law is shown to be effective even for (1) large polar to transverse inertia ratios, which increases the stored energy density while causing the poles to become more speed dependent, and for (2) low bandwidth controllers shaped to suppress high frequency noise. Passive vibration dampers are designed to reduce the vibrations of flexible appendages of the satellite. Notch, low-pass, and bandpass filters are implemented in the AMB system to reduce and cancel high frequency, dynamic bearing forces and motor torques due to flywheel mass imbalance. Successful IPAC simulation results are presented with a 12% initial attitude error, large polar to transverse inertia ratio (IP∕IT), structural flexibility, and unbalance mass disturbance.

The goal of this paper is to study the dynamics of a quadcopter using a variable geometry structure and discuss the advantages of using the geometry variation. A mathematical model has been described using simulation to show quadcopter dynamics. Based on the different geometric configurations of arms it is shown how the arms’ angles affect longitudinal and lateral dynamics. The design's assumptions refer to hovering and rotation with Euler angles. Simulation results show that both controllers stabilize the quadrotor and the amplitude of the vibrations is significantly decreased, compared to the vibration of a common quadcopter with fixed arms, by varying the arm's angle. The quadcopter remains stable and all Euler rotations are perfectly controlled.
