In today's world of signal processing, nonlinear systems have been attained a considerable importance in the field of system identification and system control. The modeling of many physical systems was introduced by a nonlinear Wiener model consists of static nonlinear function followed by a linear time invariant (LTI) dynamic system. The output of the nonlinear function is considered to be continuous...
Glow Swarm Optimization(GSO) and Particle Swarm Optimization(PSO) algorithms are proposed in this paper for optimal tuning of PI controllers for Load Frequency ControUer(LFC) design. To visualize the effectiveness of the proposed method, a two area interconnected power system is considered as a test system. To prove the robustness of the proposed controller and to stabilize the frequency of oscillations,...
In this paper, a novel fast phase detection system for all-digital phase locked loop (ADPLL) is presented. The phase detection system is realized by generating an analytic signal using a compact implementation of Hilbert transform and then simply computing the instantaneous phase. 16-bit CORDIC algorithm is employed in order to obtain the phase information of the signal. All the components used in...
