摘　　要：针对热工对象具有慢时变性的特点，提出一种将其近似为时不变系统的方法。利用该方法离线建立的系统预报模型，具有在线计算量大为减少的优点。并把单输入、单输出的多步自校正方法推广到了多输入、单输出系统。计算机仿真表明本方法是确实可行的。This paper put forward a method by which the controlled object with slow time varying character in thermal system can be approximately expressed as a time unvarying one. Using the off line built prediction model based on this method, not only the on line calculation is remarkably reduced, but also the multi step self rectifying prediction for SISO system can be promoted to the MISO system. Computer simulation shows that this method is feasible.
