Electrical machinery plays a very important in industry and everyday life hari. Exsitasi or starting means used by man to ignite drive the electrical machinery. The way exsitasi machines taken get good efficiency power torque efficiency. Thus it takes piece of equipment that is capable performing with small big torque. Inverter more commonly known as VSD (Variable Speed Drive) one option which ...

In this paper tuning of PID Controller for higher order system is given. Conventionally higher order system is reduced to lower order model, and then controller is designed. But in this method higher order system is considered as it is and controller designed based on desired Phase Margin (PM) method. Analytical expression for controller design is given which is based Mikhalevich method. The Mi...

A performance assessment procedure for single-input-single-output (SISO) and multi-input-multi-output (MIMO) systems based on modified relay feedback test is proposed in this paper. The well-known robustness measurements, gain and phase margins, are used to assess the performance of the control systems. The proposed method can on-line estimate the gain and phase margins for systems with both un...

Engineers have a range of methods to estimate the fatigue life under multiaxial conditions. Each of these predictive methods is generally subjected to restrictions, related to the inherent simplified assumptions. The objective of this paper is to evaluate the validity of commonly used multiaxial fatigue criteria for different multiaxial loading conditions. The best criterion is identified throu...

Network architectures in which the control plane is decoupled from the data plane have been growing in popularity. Among the main arguments for this approach is that it provides a more structured software environment for developing network-wide abstractions while potentially simplifying the data plane. As has been adopted elsewhere [11], we refer to this split architecture as Software-Defined N...

This paper presents a neural network predictive controller for three phase inverter fed induction machine speed control. Thus the three phase inverter fed induction motor drive has been simulated with and without step change using NNP controller. The performance comparisons of neural network predictive controller are achieved with the help of IAE (Integral absolute error) and ITAE (Integral tim...

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

in this paper, the driver with antiwindup and fuzzy high-performance and robust pi controller has been suggested for permanent magnet synchronous motor (pmsm). this controller is suggested for the design of the robust driver for three phase pmsm and the cost reduction of its control system. it’s useful for the industrial application and automation and ultimately speed control and the improvemen...

Smart reconfiguration of a dynamic networking environment is offered by the central control of Software-Defined Networking (SDN). Centralized SDN-based management architectures are capable of retrieving global topology intelligence and decoupling the forwarding plane from the control plane. Routing protocols developed for conventional Wireless Sensor Networks (WSNs) utilize limited iterative re...

This paper investigates the performance of different control schemes applied on a 5-link biped robot by simulation studies. The primary controller are implemented with a conventional Proportional Derivative (PD) controller and Computed Torque controller, later enhanced with Active Force Control (AFC). The mathematical modeling and motion control for a bipedal walking robot in this paper consist...
