Model order reduction plays an important role in the analysis of high-order systems. The main advantage of this approach is that higher order model can be converted into lower order model while retaining its essential characteristics. In literature, most of the research development in this direction is related to mathematical theory without using real time applications. In this paper, a well-known...
The power converter is a critical component of distributed generation system, particularly for renewable energy system based distributed generators. This paper presents a PV based boost converter with closed loop control by the use of PID controller. The PV module is modelled in MATLAB-Simulink Environment and is directly fed to the boost converter and the duty ratio control is obtained by means of...
This study presents an improved method for first-order plus dead-time (FOPDT) model identification from less step response data. Firstly, B-spline series expansions are used to approximate step responses, providing effective interpolation values for modeling computation. Then, to enhance modeling accuracy, a least-squares method with a regressive compensation scheme is proposed, which adaptively adjusts...
A new method for modeling the thermal response of semiconductor devices such as light-emitting diodes (LEDs) from temperature measurements is presented. The method uses a realization-theoretic approach to identification combined with convex optimization methods. Linear matrix inequalities are constructed to guarantee that the identified discrete-time model has strictly real eigenvalues between 0 and...
System modeling and computer aided simulation have been increasingly used in vehicle engineering to reduce development time, improve and simplify complex systems. A Type C Electronic Power Steering (EPS) modeling and simulation program has been developed based on Matlab. The aim of this simulation is to simulate completed system dynamic behavior regarding optimizing main parameters of system model.
To facilitate control-oriented model identification during closed-loop system operation, a low-order model identification method is proposed in this paper, based on using closed-loop step response test. By introducing a damping factor to the closed-loop step response for realization of the Laplace transform, a frequency response estimation algorithm is developed in terms of the closed-loop control...
The diode laser welding process is a typical nonlinear system with disturbances and noises. To obtain unbiased estimates for unknown parameters, an identification method based on correlation functions is preferred. In this paper, a nonlinear identification method based on crosscorrelation functions is used to establish a nonlinear model, which is linear in parameters, for the diode laser welding process...
