In this paper, the digital controller design for compensating the dc-dc buck converter output voltage has been analyzed in the digital domain. The main idea of this paper is patterning the samples of high order ideal controller and using integral square error in determining digital PID coefficients. This approach provides higher precision of digital controller design and eliminates the need for...

the main purpose of this article is to present an approximate solution for the two-dimensional nonlinear volterra integral equations using legendre orthogonal polynomials. first, the two-dimensional shifted legendre orthogonal polynomials are defined and the properties of these polynomials are presented. the operational matrix of integration and the product operational matrix are introduced. th...

This paper presents a case study of the setpoint tracking performance proportional integral derivative (PID) controller on Single-Input Single-Output (SISO) and Multi-Input Multi-Output (MIMO) nonlinear digital plants under Gaussian white noise constant load disturbance for time-delay dynamic system. With objective getting better understanding discrete-time PID controller, we proposed using two...

Given a polygonal curve P in three-dimensional (3-D) space, the polygonal approximation (PA) problem in this research is to 7nd a polygon P′ to approximate P either with the minimal polygonal segments under a given error or, conversely, with the minimal error under a speci7ed number of segments allowable. The former PA problem is called the PA-# problem; the latter PA problem is called the PApr...
