摘　　要：换热器换热系统是一个复杂的非线性系统,通过分析换热器的动态特性,结合永磁同步伺服电机在转速控制方面响应快、精确、节能的优势,提出将基于滑膜观测器的永磁同步伺服电机控制技术与换热器温度自整定模糊PID控制组成换热系统的串级控制,并在Simulink中对控制系统进行了仿真。仿真试验结果表明,结合这2种控制算法,通过改变电机转速来调节换热器流体进口流量,可以达到换热器出口温度的节能和精确控制的效果。Heat exchanger system is a complex nonlinear system,analyzing the dynamic characteristics of the heat exchanger,combined with permanent magnet synchronous servo motor with the advantage of response fast,precise,energy-saving in speed control,proposed based on synovial observer permanent magnet synchronous servo motor control technology and heat exchanger temperature fuzzy self-tuning PID control the composition of the heat exchanger cascade control system and simulation in Simulink these two control methods. The results show that the combination of these two control algorithms,by varying the motor speed to regulate the flow of heat exchanger fluid inlet,can achieve energy-saving heat exchanger outlet temperature,precise control effect.
