针对工业控制过程中的实际问题，对神经网络预测控制进行了深入的研究，提出 了两种新的智能预测控制算法。并结合混合仿真平台，以平台中非线性单变量与多变量系 统为控制对象，将部分算法应用于实际控制中。(For industrial control in the process of practical problems, neural network predictive control of an in-depth research, we propose two new intelligent predictive control algorithm. Combined with hybrid simulation platform to platform non-linear single-variable and multi-variable system for the control of objects, some of the actual control algorithm is applied.)
