A novel approach of order diminution using time moment concept with Routh array and salp swarm algorithm

In control engineering, there may be two systems that have the same input-output characteristic with differentdegrees of complexity. This concept leads to order diminution(OD) a large scale system. this article, authorspropose new hybrid diminution technique based on time moment matching method Routh arrayconcept and recently developed fast accurate salp swarm optimization (SSO) technique. The proposed methodcombines advantages both classical OD unknown coe?icient ofthe divisor reduced system is obtained by exploring methodology arrayconcept, whereas coe?icients dividend polynomial are SSO momentmatching array ensures nature in terms stability, better search capability theSSO reduces error between original diminished tested ondifferent benchmark problems, including time-delay An intensive comparative study different errors,time, frequency domain provides performance compared existing techniques. Agood match parameters transient specifications indicates success Comparatively,the rise time, settling maximum overshoots 99.6076%,99.1611%, 100%, respectively.
