摘　　要：热工过程控制具有非线性、大迟延、大滞后、时变、耦合性和不确定性的特点,从而使控制难以得到满意的效果。而广义预测控制具有较强的鲁棒性、对模型要求低的特点,并且适用范围非常广泛。本文介绍了广义预测控制的基本原理和特点,并采用隐式广义预测算法在MATLAB中对单输入单输出系统进行验证。仿真结果表明该算法不仅大大减少了计算量,而且具有较好的控制效果。Thermal process control with nonlinear, large delay, large time delay, time-varying, coupling and uncertainty of the characteristics, so that the control is difficult to be satisfied with the results. Generalized predictive control with strong robustness, low requirement on the model characteristics, and the scope is very wide. This article describes the basic principles of generalized predictive control and characteristics, and the use of implicit generalized predictive algorithm in MATLAB for single-input single-output system for authentication. The simulation results show that the algorithm not only greatly reduce the amount of computation, but also has better control effect.
