针对钨碱煮工艺过程的不连续、大时滞、非稳态等特点以及生产现场采用PID控制或人工经验调节钨碱煮过程温度难于满足工艺要求的问题，分别研究了广义预测控制（GPC）和自适应广义预测控制（AGPC）对钨碱煮工艺温度的控制，设计了基于GPC和AGPC的钨碱煮工艺温度控制系统，并分别做了MATLAB仿真分析。结果表明：钨碱煮工艺温度AGPC控制系统的超调量小、整定时间短，对系统参数时变和外界干扰的鲁棒性强，且优于GPC控制，能较好满足钨碱煮工艺温度的控制要求。
針對鎢堿煮工藝過程的不連續、大時滯、非穩態等特點以及生產現場採用PID控製或人工經驗調節鎢堿煮過程溫度難于滿足工藝要求的問題，分彆研究瞭廣義預測控製（GPC）和自適應廣義預測控製（AGPC）對鎢堿煮工藝溫度的控製，設計瞭基于GPC和AGPC的鎢堿煮工藝溫度控製繫統，併分彆做瞭MATLAB倣真分析。結果錶明：鎢堿煮工藝溫度AGPC控製繫統的超調量小、整定時間短，對繫統參數時變和外界榦擾的魯棒性彊，且優于GPC控製，能較好滿足鎢堿煮工藝溫度的控製要求。

The characteristics of tungsten alkali leaching, such as discontinuity, large delay, unsteadiness, and temperature control by PID or artificial regulating contributed to its inadequacy to meet the technological requirements. This paper studied temperature control methods in tungsten alkali leaching by GPC AGPC by designing temperature control system based on GPC and AGPC. MATLAB simulation results showed control system of AGPC enjoyed the advantages of less overshoot and setting time, stronger robustness to the system parameter time-varying and interference in comparison with GPC control.
