Control of Electric Power Plants and Systems
IFAC Proceedings Volumes, 1987Abstract Control of power systems with the improvement of stability in view has a very strong impact on planning and operation of a system. The development of devices as well as the analytical methods contribute to a large degree to the performance of present-day systems.

Real-Time Fuzzy Control of Electric Power Systems
IFAC Proceedings Volumes, 1993Abstract In this paper, the application of a real-time fuzzy controller is presented in order to improve the power system stability. The above is done with the means of the fuzzy membership functions whose values are computed depending on the measured generator frequency and voltage.

Distributed H∞-based control of Electrical Power Systems
IFAC Proceedings Volumes, 2010Abstract We consider the optimal network frequency control in electrical power systems. The overall power system consists of several subsystems distributed over a network. We implement a method of synthesizing a distributed dynamic output feedback controller (Langbort et al., 2004a) for such a system consisting of several subsystems distributed over ...

Sensorless control of Electric Power Assisted Steering system
2012 20th Mediterranean Conference on Control & Automation (MED), 2012This paper deals with the sensorless control of Electric Power-Assisted Steering (EPAS) system with the permanent magnet synchronous motor (PMSM) using sliding mode techniques. Using steering wheel angle and motor currents measurements, two cascaded sliding mode observers with unknown inputs are designed.

Robust control of electric power-assisted steering system
2005 IEEE Vehicle Power and Propulsion Conference, 2005EPS (electric power-assisted steering) system has been used to replace traditional hydronic power steering system in vehicles. In an EPS system, the assisting torque is from an electric motor for steering effort. The performance of an EPS system requires that the system can take care the road reaction torque so that the driver could feel comfortable ...

Optimal control of electric power-assisted steering system
Proceedings of 2005 IEEE Conference on Control Applications, 2005. CCA 2005., 2005EPS (electric power-assisted steering) system has been used to replace traditional hydronic power steering system in vehicles. In an EPS system, the assisting torque is from an electric motor for steering effort. The performance of an EPS system requires that the high frequency external disturbance in road reaction torque be attenuated so that the ...

A structure-based modeling and control of Electric power systems
Automatica, 1997This paper addresses the modeling and closed-loop control of large-scale electric power systems operating under normal conditions. A new structure-based modeling approach is introduced—an approach which reveals fundamental properties of power system dynamics, and offers physical insight into the interactions between its constituent subsystems.

Electrical Engineering in Japan, 2012
SUMMARYIn a future electric power system with a high penetration of photovoltaic power generation systems (PVSs), surplus power may occur during the daytime in the spring or fall when electricity demand is low. Suppressing the PVS power output as well as absorbing the surplus power by using electric storage facilities is a possible countermeasure.

Control of Active Filters in Electrical Power Systems
IFAC Proceedings Volumes, 1987Abstract Until now Var compensators with active filters are not in use in electrical power systems. One reason of this is the lack of a suitable concept of control. This paper describes a control scheme of active filters with a good dynamic behaviour. By the realization of this control concept two problems have to be solved.
