摘要
在CADCS的设计中,线性系统的结构是可以用参数表达的,但非线性系统的表达式却没有这样简单的形式,最简单且理想的方法是用表达式本身。 编译型的高级语言是不能接受一个表达式的,为了直接输入非线牲函数表达式,我们引入了一个软体运算器,它具有一套指令系统,根据非线性函数表达式可由一个编译系统自动编译计算该表达式及其任意偏导值的程序,这些程序由软体运算器执行。
In CADCS, the construction of linear system can be expressed with pa-rameters, but nonlinear system can notAn expression can not be accepted by compiled high level language. To be able to input nonlinear system expression, we introduce an arithmatic unit by software, which has the following instruction system:OP P1 P2 rOP' P1 P1' P2 P'2 rAn nonlinear expression is compiled automatically by a compiler sys-tem, thus, evalution of the expression and its partial derivatives can be achieved, which is executed on the software arithmatic unit.The system has been implemented on IBM PC/XT. These results can be used in CAD for optimal control, nonlinear system control and simulation and adaptive prediction.
