This paper considers linear shift invariant descriptor systems, in which dynamic model changes at a given instant of commutation. A sub-optimal state feedback gain is characterised which minimises discontinuities at commutation as well as an LQ cost criteria.
This note encompasses the robust stability of linear hereditary systems with state-delay. The delay is time-varying with arbitrary finite time evolution rate. The uncertainty taken into account is assumed to be of polytopic type. A less conservative delay-dependent linear matrix inequality (LMI) method is presented based on a new Lyapunov-Krasovskii functional. Descriptor model transformation has...
This work focuses on the design of a linear quadratic Gaussian controller for three degree of freedom helicopter. This system is developed at PIEAS for studying the dynamics of multi-input multi-output system. The system is underactuated having three degrees of freedom and two actuators. The outputs of the system are phi, thetas positions in the horizontal plane and in the vertical plane as well as...
