Order Abatement Technique Based on Squirrel Search Optimization Algorithm & Pade Approximation Method

This paper presents a mixed order abatement strategy for High Order Linear Dynamic Systems (HOLDSs). In this article, Pade Approximation Technique is employed to reduce the original HOLDSs' denominator and the Squirrel Search Optimization Algorithm (SSOA) yields the reduced numerator. The advantages of the two above approaches are combined to create the abated system. The aim of suggested method is to maintain the properties of the HOLDSs while minimizing the Integral Square Error (ISE). The proposed method ensures the steady state stability of the original HOLDSs and the conservation of transient stability. A thorough comparative analysis has been undertaken, examining two examples of high-order linear dynamic systems (HOLDSs). Calculation and plotting of the ISE, frequency response and time response are done using Simulink/MATLAB and the results are analyzed with various reduction methods found in the published work. As compared to other techniques, the findings show that the recommended strategy offers a reduced ISE and the time and frequency response closely match the original system's response.
