By using the quasi steady state and mixed modeling methods, the nonlinear mathematical model of the ship main propulsion system is established. An improved integrated control algorithm based on CMAC and PID is presented in the ship propulsion system. Simulation computing is completed to investigate the dynamic characteristics of the ship propulsion system on rough sea conditions. The results show...
An intelligent supervision control for ship roll motion stabilization is presented in this paper. The control system consists of a linear PID controller based on ship fin stabilizer three parameters, an inverse model wavelet neural network (IMWNN) controller and a wavelet neural network identification (WNNI). The linear PID controller is adopted to carry out feedback control. The WNNI is used to learn...
Aiming to the control feature of large delay system like ships, designing a 2-rank derivative multi-step neural network predictive model and the algorithm, and presenting a fuzzy control scheme based on the model with PID neural network and fuzzy CMAC controller, we solve the problems of model online identification and controller online design in traditional adaptive control, so that the high precision...
Asymmetric information theory was introduced in this paper. For a nonlinear course keeping system for ships, the PID parameters were tuned using profound exact feedback linearization algorithm and closed-loop gain shaping algorithm. A nonlinear robust PID controller was designed; the information transmitting capacity was strengthened through simplifying the exact feedback linearization controller...
