水力发电机组是一个复杂的非线性控制对象,为保证水电站发电机组功率调节具有快速、稳定的控制特性及良好的鲁棒性,本文提出在水电站计算机监控系统有功功率调节中采用单神经元自适应PID功率调节方式.PID控制的关键问题是PID参数的整定,单神经元自适应PID控制器由于其权值可以在线调整,具有较强的自学习和自适应能力,仿真结果表明改进的单神经元PID控制器比传统的控制器拥有更好的稳定性、动态性能和鲁棒性.

Study on single neuron adaptive PID controller in power regulation of hydropower station computer monitoring system

Hydroelectric generating unit is a complex nonlinear controlled object.In order to improve the performance of power regulation in hydropower station computer monitoring system,an advanced single neuron adaptive PID controller was used in power control in hydropower station computer monitoring system.The main factor in classical PID controller is its pa- rameters.The control unit of single neuron adaptive controller is a PID control too.Due to its parameters could adjustable on- line,so it has good ability on self-study and self-adaptive.Simulative result shows that the advanced single neuron adaptive PID controller is better than classical PID controller in stability,dynamic performance and robustness.
