This paper presents the establishments of sea water disturbance, ship roll motion and a design of simplified fuzzy controller (SFC), a class of fuzzy controller which is developed to improve the efficiency of real-time implementation when it is applied to the fin stabilizer. The triangle membership function, simplified Larsen product inference and formulated fuzzy role base are adopted in SFC, focusing...
In this work, we apply fuzzy RBF neural network to address the traffic density control problem in a macroscopic level freeway environment with ramp metering. Firstly, a macroscopic traffic flow model to describe the freeway flow process is built. Then the architecture and function of fuzzy RBF neural network are analyzed. In conjunction with nonlinear feedback theory, a PID ramp controller regulated...
Aiming at the nonlinear and time-varying characteristics of freeway traffic system, a fuzzy self-adaptive PID controller is designed and applied to freeway ramp metering in this paper. A traffic flow model to describe the freeway flow process is firstly built. Based on the model and in conjunction with nonlinear feedback theory, a fuzzy-PID ramp controller is then designed. The ramp metering rate...
