摘　　要：在介绍多温区控制系统的基础上，针对实际多变量、强偶合的非线性温控系统，设计了自适应拟人智能控制策略。采用了分区控制思想，根据不同的误差和误差变化趋势，采取不同的PID控制策略；为了更好地克服各种外界因素的影响，加入误差观测器在线修正参数和前馈补偿控制；同时，为了有效地克服系统时滞特性的影响，进一步引入了滞后补偿控制的方法：仿真和实际运行结果表明了该控制策略的有效性和实用性.Control strategy of self-adaptive human-imitating intelligent control is presented in this article, and a muhivariable and strong couple nonlinear temperature system and divisional control strategy is introduced. Different PID control strategy, together with Error observer for adjusting parameters online and control of feed-forward compensation, is adopted according to different error and its derivation to overcome the exoteric influence. At the same time, the control strategy of lag compensation is accordingly adopted in order to overcome the effect of lag characteristic, the simulation and application prove that the control strategy is very effective and practical.
