摘要
基于无模型自适应的基本理论,针对火电厂主汽压系统的特点,将无模型控制器与比例积分控制器作为主、副调节器构成串级控制,应用于主汽压控制系统以改善控制性能。仿真试验表明,该控制方案能快速消除燃料量内扰并对被控对象模型的大范围变化表现出强鲁棒性。
Based on fundamental principles of model-free adaptive control and characteristics of main steam pressure system in thermal plant, a MFAC-PI cascading control system is designed, and simulated on main steam pressure system, in order to improve control performance. It is proved that the control structure can overcome fuel disturbance quickly, be more adaptive to load change and be more economical.
