The method of solving the time-delayed parameter difficult choice in controlling chaos was proposed in this paper. The fuzzy control method was applied into chaotic control by time-delayed feedback. The quadrature-axis stator voltage was used as the manipulated variable. The input of the fuzzy controller was the system error. Fuzzy controller searched the optimum time parameter according to the error...
Meeting with high efficiency permanent magnet motor developing, a hybrid algorithm of PSO (particle swarm optimization) and chaos is proposed to solve magnet optimization problems. It is used the fast convergence of PSO and ergodicity, randomicity, and regularity of chaotic motion in the spinning motor magnet optimization, and validated by practice application. The designed motors have carried out...
By using the two methods of Lyapunov exponent and power spectra analysis, it is tested and verified that chaotic phenomenon exists in time sequence of distance information that autonomous mobile robot has got from sensors between robots and obstacles. The complexity of path planning for autonomous mobile robot through sensors is explained under dynamic environments by use of chaotic phenomenon. The...
The problem of the delay-time parameter difficult to be determined in controlling chaos was considered in this paper. The quadrature-axis stator voltage was used as the manipulated variable. Applied the fuzzy control method into chaotic control by time-delayed feedback. The input of the fuzzy controller was the difference between the feedback of output and the set value of system. Fuzzy controller...
The surging phenomenon appearing in thruster motor system may affect the stability, reliability and safety running of deepwater robot. This paper seeks to introduce an improved calculation algorithm of largest Lyapunov exponent by use of non-linear chaos theory analysis and study. The Lyapunov exponent of thruster motor system is calculated respectively in different work circumstance, of which the...
