Examination of Transmission Zeros in the MIMO Sensor-Based Propagation Environment Using a New Geometric Procedure.

In this paper, we propose the application of a new geometric procedure in order to calculate a set of transmission zeros of a propagation environment. Since the transmission zeros play a crucial role in modern communication systems, there is a need to apply the efficient solutions characterized by a maximum speed operation. It turns out that the classical method based on the Smith-McMillan factorization is time-consuming, so its contribution to the detection of transmission zeros could be unsatisfactory.

Perfect control for nonminimum-phase unstable systems defined in the multivariable continuous-time state-space framework - An inverse-based approach.

In this paper, a new perfect control law dedicated to nonminimum-phase unstable LTI MIMO systems governed in the continuous-time state-space domain is proposed. Two algorithms are investigated, one of which has turned out to be definitely accurate. Henceforth, the inverse model control-based formula can be applied to any right-invertible plants having more input than output variables.

A Sensor-Aided System for Physical Perfect Control Applications in the Continuous-Time Domain.

The recently introduced continuous-time perfect control algorithm has revealed a great potential in terms of the maximum-speed and maximum-accuracy behaviors. However, the discussed inverse model-originated control strategy is associated with considerable energy consumption, which has exceeded a technological limitation in a number of industrial cases. In order to prevent such an important drawback, several solutions could be considered.

A Measurement-Aided Control System for Stabilization of the Real-Life Stewart Platform.

In the paper, an innovative control system devoted to the stabilization of the parallel manipulator-type Hexapod is presented.

Indeed, the telescopic boom located on the car along with the system providing the correction of the boom column deflection as well as the gyroscopic self-leveling head constitute a complex tool covering a plethora of modern techniques and solutions.

Improvement of Baro Sensors Matrix for Altitude Estimation.

The article presents the use of barometric sensors to precisely determine the altitude of a flying object. The sensors are arranged in a hexahedral spatial arrangement with appropriately spaced air inlets. Thanks to the solution used, the range of measurement uncertainty can be reduced, resulting in a lower probability of error during measurement by improving the accuracy of estimation.
