The paper reviews modeling of thyristor–controlled series capacitors (TCSC) which are highly nonlinear systems with continuous and discontinuous states, and proposes three nonlinear controllers for it: (1) An approximate feedback linearization control (FLC) (2) A sliding surface–like design (3) Control in transformed coordinates. Detailed (switched) time– domain simulations are used to verify t...

Sliding mode control algorithms with classical and modified discontinuous reaching laws for purely magnetic attitude control of small satellites are proposed and compared with each other in this work. They are designed by following the steps characteristic to the variable structure control method and the magnetic attitude control problem. The asymptotical stability of the control laws is proven...

Discrete-time stochastic systems employing possibly discontinuous state-feedback control laws are addressed in this paper. Allowing discontinuous state-feedback control laws is in fact fundamental for stochastic systems regulated, for instance, by optimization-based control laws. We introduce generalized random solutions for discontinuous stochastic systems in order to guarantee existence of so...

abstract introduction: critical thinking skills as thinking and judging self-regulation are purposeful and result in solving problems and making appropriate decisions. therefore, the importance of this subject and its role in the nursing profession and the clinical decision, this study was done to compare critical thinking skills of nursing students in continuous licentiate and bachelor- licent...

Three discontinuous operating modes of PWM converters are considered in this paper-the discontinuous inductor current mode (DICM), the discontinuous capacitor voltage mode (DCVM) and a previously unidentified mode named discontinuous quasi-resonant mode (DQRM). DC and smallsignal ac analyses are applicable to all basic PWM converter topologies. Any particular topology is taken into account via ...
