Robust output-feedback simplified adaptive control model following is considered for discrete-time systems with uncertainties and disturbances. Sufficient conditions for closed-loop stability, model following performance and prescribed H∞ disturbance attenuation level are introduced, under an almost-strictly-positive-realness requirement on the plant. A numerical example, taken from the field o...

A probabilistic model of human control behaviour is described. It assumes that human behaviour can be represented by switching among a number of relatively simple behaviours. The model structure is closely related to the Hidden Markov Models (HMMs) commonly used for speech recognition. An HMM with context-dependent transition functions switching between linear control laws is identified from ex...

The present quasi-experimental study mainly investigates the role of literature as input for reading comprehension in Iranian EFL classrooms. To be more exact, it investigates the effects of authentic and simplified literary texts on the reading comprehension of Iranian advanced EFL learners. The participants were 35 male and female Iranian EFL learners who were at advanced level, studying in a...

Elaborated models such as those used for simulation purposes (e.g. OLGA simulator) cannot be used for model-based control design. The focus of this paper is on deriving simple dynamical models with few state variables that capture the essential behaviour for control. We propose a new simplified dynamic model for severe slugging flow in pipeline-riser systems. The proposed model, together with f...

This paper deals with the control of a thrust vectored flying wing known as the ducted fan, developed at California Institute of Technology. The experiment was developed to serve as a testbed for nonlinear control design. In an earlier paper, the authors reported simulation results based on a simplified (no aerodynamics involved) planar model of the ducted fan around hover position. In this pap...

The contribution is focused on helicopter elevation control. The experiments are performed on helicopter model, which is significantly nonlinear plant and it simulates in some simplified way dynamics of real helicopter. There is derived new way to control it which uses piecewise-linear neural model. As it is shown at the end of the paper, this new control algorithm brings decent performance imp...
