摘　　要：提出了一种以经典PID为基础,用单神经元加以实现的智能PID控制算法。基于误差二次型最优理论推导出相应的单神经元输入权值参数调整算法。并推导了为改进其应用上的不足,将自适应PSD控制器中递推计算增益K的方法应用到单神经元的自适应PID控制,构成具有自动调整增益K值的单神经元自适应PID控制器的学习算法。将控制算法应用到航天器姿态控制系统,数字仿真结果验证控制器有效。Based on classical PID, an intelligent PID calculation is developed using single neuron. The adaptation law for adjusting the weights of the single neuron is proposed based on quadratic form of the system error. In order to improve the arithmetic, a king of self - correcting gain K adaptive PID control way is presented by using recursion formula of gain K in adaptive PSD controller. The way is used in spacecraft attitude control system. The effectiveness of the controller is demonstrated by the simulation.
