     seeker optimization algorithm (soa) is a new heuristic population-based search algorithm. in this paper, soa is utilized to tune the parameters of both single-input and dual-input power system stabilizers (psss). in soa, the act of human searching capability and understandings are exploited for the purpose of optimization. in soa-based optimization, the search direction is based on empirical gradient by evaluating the response to the position changes and the step length is based on uncertainty reasoning by using a simple fuzzy rule. conventional pss (cpss) and the three dual-input ieee psss (namely pss2b, pss3b and pss4b) are optimally tuned to obtain the optimal transient performances. from simulation study it is revealed that the transient performance of the dual-input pss is better than the single-input pss. it is further explored that among the dual-input psss, pss3b offers the best optimal transient performance. while comparing the soa with recently reported optimization algorithms like bacteria foraging optimization (bfo) and genetic algorithm (ga), it is revealed that the soa is more effective than either bfo or ga in finding the optimal transient performance. sugeno fuzzy logic (sfl)-based approach is adopted for on-line, off-nominal operating conditions. on real time measurements of system operating conditions, sfl adaptively and very fast yields on-line, off-nominal optimal stabilizer parameters.
