چکیده
This paper proposed a new approach of controller design. By using model matching method we design a PID controller for higher order system. A higher order model is reduced by Pade approximation and mixed method, then design a controller for reduced order model. We take a comparatively study between close loop response of higher order system and reduced order system. The model order reduction and controller design is illustrated through a numerical example. KeywordsReduced order model, Pade approximation, Mixed methods, Model order reduction, PID controller, Model matching method.

Controller Design for Linear Time Invariant System with Improved Pade Approximation
In this paper, the model order reduction phenomenon is implemented using the pade approximation method to obtain a second order reduced model for stable linear time invariant continuous system. A controller is designed for the reduced second order model to meet the desired performance specifications. This controller is attached with the reduced order model and closed loop response is observed....
متن کاملRadar Signal Detection in K-distributed Clutter by Pade Approximation
In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...

Using H∞ control, the design problem is formulated in terms of user defined weighting polynomials on the process closed-loop Sensitivity functions to achieve desired closed-loop performance and robust stability in the presence of process modelling error. In this paper stability conditions , in terms of the process sensitivity functions, are derived for processes containing a pure time delay for...
متن کاملOrder Reduction using Modified Pole Clustering and Pade Approximations
The authors present a mixed method for reducing the order of the large-scale dynamic systems. In this method, the denominator polynomial of the reduced order model is obtained by using the modified pole clustering technique while the coefficients of the numerator are obtained by Pade approximations. This method is conceptually simple and always generates stable reduced models if the original hi...
