This paper considers sliding mode allocation schemes for fault tolerant control. The schemes allow redistribution of the control signals to the remaining functioning actuators when a fault or failure occurs. The paper analyzes the schemes and determines conditions under which closed–loop stability is retained for a certain class of faults and failures. It is shown that faults and even certain t...

This paper presents a control strategy of large-scale wind-thermal power joint primary frequency regulation. First, an integrated is established rotor kinetic energy and pitch angle for wind turbine generators participation in regulation within wide range velocity; Second, fuzzy PI controller designed the recovery turbine, which can avoid occurrence secondary drop accident during generator exit...

Many types of vehicle control systems can conceivably be developed to help drivers maintain stability, avoid roll-over, and customize handling characteristics. A lack of state and parameter information, however, presents a major obstacle. This dissertation presents state and parameter estimation methods using the Global Positioning System (GPS) for vehicle dynamics control. It begins by explain...

In the present paper, the controlled flight of fruitflies after voluntary takeoff is studied. Wing and body kinematics of the insects after takeoff are measured using high-speed video techniques, and the aerodynamic force and moment are calculated by the computational fluid dynamics method based on the measured data. How the control moments are generated is analyzed by correlating the computed ...

In this study, the Deep Deterministic Policy Gradient (DDPG) algorithm, which consists of a combination artificial neural networks and reinforcement learning, was applied to Vertical Takeoff Landing (VTOL) system model in order control pitch angle. This algorithm selected because conventional algorithms such as Proportional Integral Derivative (PID) controllers cannot always generate suitable s...

Minsik Park et al. 1 http://dx.doi.org/10.4218/etrij.14.2113.0086 A holographic display system with a 22-inch LCD panel is developed to provide a wide viewing angle and large holographic 3D image. It is realized by steering a narrow viewing window resulting from a very large pixel pitch compared to the wave length of the laser light. Point light sources and a lens array make it possible to arbi...
