摘要
为了克服锅炉燃烧系统多变量、强耦合、强干扰、大滞后的特性,提出了基于状态空间方程的模型预测算法控制(MAC)与PID控制相结合的新型多变量PID-MAC算法,并采用李雅普诺夫第二方法证明该算法导出的控制律可使控制系统闭环、稳定。以燃气锅炉燃烧系统为对象,通过仿真试验证明了该算法不仅具有PID控制稳态误差小、上升时间短以及超调小的优点,而且在一定程度上克服了PID控制调节时间长和模型算法控制稳态误差较大的不足。
To overcome the complex features of boiler combustion system,such as multivariable inputs and outputs,strong coupling,strong interference and long hysteresis,a new multivariate PID-MAC algorithm combing the state-space equation based model algorithm control（MAC）with the PID control was proposed.Moreover,the Lyapunov＇s second stability theorem was employed to prove this algorithm renders the system closed-loop stabilization.Simulation experiments with gas boiler show this control strategy has advantages like small steady-state error and short rise time during PID control,and small overshoot of MAC.Furthermore,to some extent,it gets rid of long regulation time of PID control and large steady-state error of MAC.
