Objective: This dissertation explores the influence of pectoral fin structures at different swimming modes on a robotic fish's locomotion behavior; Some objectives are addressed to achieve the mentioned aim as follows: Firstly, new designs based on bio-inspired pectoral fin types are constructed. Secondly, to describe fin deformation and body part movement, novel dynamically mathematical models are developed.

Propose the global – local mean square error criterion (GLOMSEC) for Gaussian equivalent linearization method (GEL) for randomly excited MDOF nonlinear system subjected to white noise or color noise excitation. The mean square of response solution will be concentrated to evaluate the accuracy of the proposed criterion by comparison with exact solution or other accepted solutions.
