摘 要:
对于具有多变量强耦合特点的工业过程对象，控制系统的稳定性是非常重要的。当输出偏离控制目标，尤其控制输出偏向非常不希望的方向时，需要较强的控制作用使输出快速返回目标值。这样就存在协调控制的快速性和稳定性之间的矛盾。本文针对这一问题，提出了以模型预测控制MPC（model predictive control）理论为基础的单边区间控制算法。通过权重区分输出偏离目标值的方向，对不同的偏离方向采取不同的控制强度，在保证快速控制的前提下最大限度满足了稳定控制的要求。本文对算法的求解进行了讨论，并通过实例仿真验证了新算法的单边区间控制功能。[著者文摘]

Abstract:
Control stability is important to the plant with multi-variable and coupling performance. When the output get away from the object, especially run to the dangerous direction, it should take hard regulating to quickly withdraw the output reture to the object. Therefore, how to solve the contradiction between speediness and stability was presented in the paper. To solve the problem, the paper proposed zone-control algorithm with unequal limits on the base of the theory of MPC, which take various control to different devious from the object through distinguishing the devious directions by different weights. In this way, it realized stability as possible as under the prediction of quickly returning the object. In addition, the solution to the algorithm was discussed and finally it was proved that the new algorithm is realizable by the simulation.[著者文摘]
