摘　　要：Simulink是基于Matlab的框图设计环境的仿真工具,可实现动态系统建模、仿真和分析。应用Simulink建立固体SCR实验控制系统,采用模块化设计,通过在环仿真,确定NH3的喷射量,运用Code Warrior软件,对MC9S12d64单片机配置寄存器和复杂接口设备。实验表明,该控制系统能够满足SCR的实验要求,NH3喷射量大小随催化器温度与空速不同而变化。Simulink is a block diagram of a design environment based on Matlab simulation tool.It can be used for dynamic system modeling,simulation and analysis.Solid selective catalytic reduction（SCR） experimental control system was established by application of Simulink,and modular design was used.According to the loop simulation,the amount of NH3 injection was determined.MC9S12d64 microcontroller interface device registers was configured by using Code Warrior software.Experimental results showed that the control system can meet the test requirements of SCR.NH3 injection amount varied according to catalyst temperature and space velocity.
