We describe a method for computing the controllable subspace of a linear periodic discrete time system. The method is based on the ordered periodic Schur form 1] by reducing the state equation to a convenient form in which the controllable/uncontrollable states are clearly displayed. Its attractive features are simplicity, numerical accuracy and stability.

A new stability theorem of the direct Lyapunov’s method is proposed for neutral-type systems. The main contribution of the proposed theorem is to remove the condition that the D operator is stable. In order to demonstrate the effectiveness, the proposed theorem is used to determine the stability of a neutral-type system in a critical case, i.e. the dominant eigenvalues of the principal neutral ...

A control system for the rotation of a multi-link machine has been developed. It increases stability movement during transportation animals and other goods in agribusiness provides over semi-trailer wheels depending on folding angle. Additionally, it is proposed to include digital unit with an adaptive module adjusting turn trajectory, taking into account inertial forces caused by displacement ...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.
