Designing a Two-Phase BLDC Motor and Finite-Element Analysis of Designing a Controller in Order to Manoeuvre High-Speed Boats in Marine Turbulences

High speed boats are small kind of boats which are piloted with boatman. These boats are usually used in strategic commissions like military which fast speeds and good manoeuvrability are of essential importance. Rough sea path، marine turbulences and multi input multi output nonlinear dynamical model of this boats،make it very difficult to pilot and manoeuvre them. in this paper،. two controller are designed and proposed for pursuing desired path and manoeuvring fast speeds. Fuzzy controller is compared with the result of PID controller. Simulation results also indicate that these proposed controllers have suitable responses and can pilot the boat in the best manner.
