This paper presents a nonlinear robust control design procedure for a micro air vehicle, which uses the singular value (μ) and μ-synthesis technique. The optimal robust control law that combines parametric and lumped uncertainties of the micro UAV (unmanned aerial vehicle) which are realized by serial connection of the Kestrel autopilot and the Gumstix microprocessor. Thus, the robust control f...

The URV is operated manually with a joystick or automatically with a computer. The automatic control of the underwater robot is a difficult problem due to its nonlinear dynamics. Moreover, the dynamics can change according to the alteration of configuration to be suited to the mission. In order to cope with those difficulties, the control system should be flexible. An interesting review of clas...

Traditionally, missile autopilots have been designed using linear control approaches with gain scheduling. Autopilot design is typically carried out in the frequency domain and the plant is linearized around various operating points on the trajectory. Moreover, three single axis autopilots are usually designed without considering the interaction among the motion axes, i.e., the autopilots in ea...

AirGuardian is a complex of an Unmanned Aerial Vehicle and ground station UAV hardware and software systems which has been developed at Obuda University. The hardware and software of the autopilot (AERObot), the antenna tracker station and the ground control station were simultaneously created resulting in the optimal cooperation of the modules. The aim of...

The traditional three-loop autopilot[11] suffers from coupling in pitch, yaws, roll channel as well as degraded performance due to huge aerodynamic uncertainties. Sliding mode control is applied to design autopilot for skid-to-turn missile (STT) missile systems to overcome the above stated difficulties. The design has two steps. The first step involves feedback linearization and the second stag...

This paper proposes an autopilot system that can be used to control the small scale rotorcraft during the flight test for linear-frequency-domain system identification. The input frequency swept is generated automatically as part of the autopilot control command. Therefore the bandwidth coverage and consistency of the frequency swept is guaranteed to produce high quality data for system identif...

We present two studies on robustness of feature extractions for an remote classroom intelligent autopilot: (1) robust feature extractions and (2) a simple automated calibration of webcams. For the robust feature extractions, use of quantified vectors is studied as feature extractions of fuzzy classifiers in Perceptual State Machine, i.e. our core Computational Intelligence model for this intell...

A tactical skid-to-turn missile autopilot is designed and implemented using a two step design process that results in an optimal output feedback with a fixed, low-order dynamic compensator for reduced design and implementation cost. The gain design consists of minimizing a performance index in which measurements and controls are appropriately weighted to achieve the desired speed of response, w...

State-dependent Riccati equation based controllers are becoming increasingly popular because of having attractive properties like optimality, stability and robustness. This paper focuses on the design of a roll autopilot for a fin stabilized and canard controlled 122mm artillery rocket using state-dependent Riccati equation technique. Initial spin is imparted to rocket during launch and it quic...
