چکیده
The positive asymptotically stable continuous-time linear systems are approximated by corresponding asymptotically stable discrete-time linear systems. Two methods of the approximation are presented and the comparison of the methods is addressed. The considerations are illustrated by three numerical examples and an example of positive electrical circuit.

Many mechanical systems are characterized by flexible joints. One of the main problems in control of this kind of devices are the mechanical oscillations. To avoid the problem of vibrations the input shaping method might be used. For the systems with variable parameters the standard methods of simple input shaping are insufficient and non-robust. More complicated algorithms, exemplary super-rob...

Comparison of several types of electrostatic micro-actuators is carried out, particularly with respect to their resultant force effects. The continuous mathematical model of such actuators is mostly described by the Laplace equation. In this paper, its numerical solution is performed by a fully adaptive higher-order finite element method, using a code developed by the authors. The methodology i...

This paper describes a discrete adaptive state feedback controller used to load current control in terms of variable DC voltage of inverter. Controller was designed by using linear quadratic optimization method. Adaptive LQR was used because of non-stationarity of the control system caused by Voltage Matching Circuit VMC. Gain values of the adaptive controller were approximated by using an arti...

متن کاملDesign of a High-Bandwidth Y-Shaped Photonic Crystal Power Splitter for TE Modes
In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitt...
