The pitch control system has a profound impact on the development of wind energy, and yet delay or non-minimum phase can weaken its performance. Thus, there is strong incentive to enhance technology in order counteract negative effects unidentified delays characteristics. To reduce complexity parameter-tuning process improve performance system, this paper, we propose novel method for turbine an...

Flapping insect flight is a complex and beautiful phenomenon that relies on fast, active control mechanisms to counter aerodynamic instability. To directly investigate how freely flying Drosophila melanogaster control their body pitch angle against such instability, we perturbed them using impulsive mechanical torques and filmed their corrective maneuvers with high-speed video. Combining experi...

This paper shows roll and pitch feedback control on a coaxial mini helicopter equipped with a center of gravity steering mechanism. The helicopter carries a minimal set of sensors to measure yaw rate, distance to ground and roll and pitch angle. While yaw rate and distance to ground control are already realized on the helicopter, roll and pitch control including the necessary signal filtering a...

Previously, we have looked at the stability augmentation system. This system can be seen as the inner loop of the aircraft control system. In this chapter, we focus on the outer loop: the control augmentation system. When we want to keep a certain pitch angle, velocity, roll angle, heading, or something similar, then we use the CAS. In this way, the pilot workload can be reduced significantly. ...

3D Virtual Environments (VE) are becoming popular as a tool for cognitive, functional and psychological assessment. Navigation in these environments is recognized as one of the most difficult activities in 3D Virtual Environments (VE). Users unfamiliar to 3D games, specially elder persons, get puzzled when they try to virtually move an avatar through these environments. Their inability to navig...

Insects produce a variety of exquisitely controlled manoeuvres during natural flight behaviour. Here we show how hawkmoths produce and control one such manoeuvre, an avoidance response consisting of rapid pitching up, rearward flight, pitching down (often past the original pitch angle), and then pitching up slowly to equilibrium. We triggered these manoeuvres via a sudden visual stimulus in fro...

This paper presents robust controller design for a wind-driven induction generator system using structured singular value ( -synthesis) method. The controller was designed for a static synchronous compensator (STATCOM) and a variable blade pitch angle in a wind energy conversion system (WECS) in order to achieve the required voltage and mechanical power control. The results indicated that this ...

Twin rotor MIMO system (TRMS) are widely used in the aerospace application. TRMS consist of two rotors one is for the horizontal moment and other for the vertical moment. These two rotors are attached on a beam for the counter balance, which ensures the safety of the helicopter. For controlling the TRMS mechanical parts and electrical circuitry are used together. In this paper multi-objective g...
