Depending on the number of terms used in Maclaurin series expansion within the design procedure one gets PI or PID controllers. In the proposed design methodology, the time constant 位 of the reference model is the free parameter, and it has a direct influence to the disturbance rejection, ...

All rational approximations for fractional order of 0.1, 0.2,鈥 , 0.9 are obtained using continued fraction expansion (CFE) method. Extension of the stability boundary locus approach to control systems with a fractional order transfer function is given for the computation of stabilizing PI and PID ...
This technique is realized by Maclaurin series expansion of the simple feedback form of a multivariable IMC controller. The IMC controller is designed to provide complete decoupled control, and is tuned either to accommodate modeling uncertainties using multivariable Mp tuning, or to get the best ...
Tuning of PID controller is achieved by conventional method whereas the PI~λD~μ is adapted the Taylor series expansion method of tuning. The various simulations are carried out in order to analyze the performance index of both the controllers and to fix the best controller, the results are ...

By employing a novel approach to the synthesis of the control systems with a time delay based on a root-locus analysis, the method eliminates errors resulting from the omission of high-order terms in the Taylor series expansion or the Pad茅 approximation in simplified mathematical descriptions of...
