摘要
针对微型燃气轮机发电系统运行过程复杂,难于建立准确的数学模型的问题,介绍了一种基于零极点配置算法的微型燃气轮机的转速控制器设计方法。它可实现在线实时辨识被控对象参数,并具备PID参数的自校正功能,提高了微型燃气轮机在变工况(被控对象参数发生变化)运行下的控制性能和对工作环境的适应能力。仿真结果证明,该控制系统响应速度快,抗干扰能力强,超调小、稳态误差小。
The running process of a microturbine is very complicate and it is very difficult to build a precise mode for a microturbine, so the self-tunning ability is very important to the controller. To this end an algorithm based on zero-pole assignment for the design of microturbine rotate speed control system is provided. This method not only identifies the parameters of control object online but also has self-tunning function on PID parameters. The experimental data shows that the control ability under the condition of changing work state and the adaptive ability on work circumstance of microturbine are improved.
