综合减摇控制系统存在非线性、多变量、强耦合等因素,会导致减摇系统达不到最佳控制状态。利用粒子群算法具有对整个空间进行高效搜索以及PID神经网络的自适应特点,提出一种改进粒子群算法,以解决粒子群算法中存在算法精度不高、粒子易陷入局部极小值等问题,并提高PID神经网络训练速度和训练精度,便于参数寻优。仿真结果表明,改进的粒子群算法具有一定优越性,将其运用到综合减摇控制系统解耦控制器设计中,能够有效地减小船舶横摇,达到较好的控制效果。
- Abstract:
-
The integrated ship stabilization system has nonlinear, multi-variable and strong coupling characteristics, which may hinder the system from reaching the best control state. An improved particle swarm algorithm is proposed based on the characteristics of particle swarm optimization (PSO) algorithm, which can search the parameter space efficiently, along with its associated PID artificial neuron network that has self-regulation and adaptability. The improved particle swarm algorithm can overcome disadvantages in former particle swarm algorithms such as low precision, the particles tend to fall into extremely small values, and so on. In addition, the improved algorithm can increase the training speed and precision of the PID nerve network, which facilitates parameter optimization. The simulation results show that the improved PSO has certain advantages, it can reduce ship rolling, and can achieve excellent control effects when it is applied to the design of the decoupling control of an integrated stabilization control system.
