Hammerstein模型是描述非线性化学过程的常用模型。Hammerstein模型的一般控制策略是非线性逆方法，但这种方法不适用于具有输入多重性的Hammerstein系统。为了克服这一困难，提出了一种多PID控制方法。因此，复杂的控制问题可以通过常规且简单的控制策略来解决。通过对换热器过程的仿真，验证了该控制方法的有效性。
Hammerstein models are popular in describing nonlinear chemical processes. The general control strategy for Hammerstein models is the nonlinearity inversion method, which is unfortunately inapplicable to Hammerstein systems with input multiplicity. To overcome this difficulty, a Multi-PID control approach is proposed. Thus, a complex control problem is solved by a conventional and easy control strategy. A Heat Exchanger process is simulated to demonstrate the effectiveness of the Multi-PID control approach.
