The paper analyzed and model of a fault tolerant electromechanical controlled worm gear driven fuel shut off valve for aerospace application. The analysis is mainly on design a reduced order fractional controller. This is for controlling the velocity of worm gear so that the friction torque due to uneven rotational speed can be avoided. Because with the friction and stiction and backlash the valve system performance is reduced and more and more unstable this leads the system to failure. The proposed controller can provide robustness against the uncertain loading torque and system parameter.

The paper presents modern advanced development methods of controlsystems that minimizes the cost of development of applications which are widely applicable in industrial control of whole range of processes. Unlike the classical way of design and testing control algorithms which are based on expensive RT measurement cards or dSpace, this solution is based on industrial controllers WinPLC/WinPAC. This enables so called rapid-prototyping of control algorithms directly from Matlab-Simulink into target platform. It was used muItiplatform controlsystem REX as a bridge between Matlab and the target platform. The paper describes whole design of control algorithms and control schemes, simulation of prepared schemes, uploading control schemes into target platform of WinPLC. Also possibilities of remote data transfer and data storage are mentioned. The real measurement on hydraulic industrial system proved its limits that were also explained in this paper.

This paper proves the uniform continuity of the value function for exit time optimal control problems of hybrid systems with autonomous and controlled transitions. By extending conditions already used for purely continuous systems the paper provides the ground for numerical algorithms for dynamic programming of hybrid systems. Transversality conditions for the continuous dynamics at the guard set boundaries ensure that the continuity property of the value function is not altered by a discrete transition of the hybrid system.

The study presented in the paper aims to investigate the control performances of an interpolative control algorithm applied on a complex nonlinear system. In the specified context, the study was made based on results obtained through simulations on a 3D-Crane. The results were compared with data obtained from a classical PID system that also incorporates the 3D-Crane.
