将多传感器信息融合理论应用于大型非线性系统的PID控制中。引入博弈算法解决了传统信息融合系统中信息冲突环境下的决策问题,实现了融合中心的多传感器交互决策。并将该模型用于丰满水电系统调速器PID控制的参数在线调整。经计算机仿真实验表明,该模型可以有效地解决原PID控制参数整定困难而导致的系统转速和频率振荡等问题。 The multi-sensor information fusion theory is applied to the PID control of large-scale nonlinear systems. The game algorithm is introduced to solve the decision-making problem under the information conflict environment in the traditional information fusion system and to realize the multi-sensor interaction decision in the fusion center. The model is used to adjust the parameters of PID control of Fengman hydropower system governor. Computer simulation shows that this model can effectively solve the problems of system speed and frequency oscillation caused by the difficulty in tuning the original PID control parameters.
