This paper deals with the simulation of a proportional-integral-derivative (PID) controller based on charge-controlled memconductor. First, the behavioral model of an incremental and decremental memconductor is built on SIMULINK under MATLAB environment. Here we will show how increase or decrease the memconductance according the width and amplitude of a positive or negative pulse signal, respectively...
The main purposes of this paper is to introduce a new floating memristor emulator circuit based on positive second generation current conveyors (CCII+s). The proposed circuit is very simple, since four CCII+s, six passive elements along with one four quadrant multiplier are only used to obtain the frequency-dependent pinched hysteresis loop of the memristor in the current versus voltage plane. An...
Practitioner engineers in both academic and industrial areas, are often faced with the challenge of identifying the model of a given system or process in order to setup a controller or to extract some useful information. Among the existing identification algorithms, those being numerically simple and stable are more attractive for practitioners. This paper deals with identification of state-space...
Tolerance to faults of control systems has been defined through the control reconfigurability concept, property defining the capacity of the control system to allow restoration of performance in the presence of faults. For its evaluation it is required to calculate the controllability gramian. This calculation is usually carried on before control system be implemented, i.e., off-line. Instead, the...
This paper provides a novel configuration to design a multi-scroll chaotic oscillator employing unity-gain cells (UGCs). The inclusion of multi-breakpoints to create a high-order negative nonlinear resistor (NR) is realized by the parallel combinations of basic cells. The breakpoints are controlled with resistors and tuning with level shifters. The multiscroll chaotic attractor has been optimized...
A new implementation of Chua's circuit employing unity-gain cells (UGC) as the active building blocks to emulate the behavior of the nonlinear resistor (NR) and the grounded inductor is introduced. The breakpoints and slopes associated to the NR as well as the numeric value of the inductor can be adjusted by the control resistors. The proposed circuit is suitable for implementation with the commercially...
