【摘要】 IBM-PC 微机用于实时仿真和实时控制的情形越来越多,而控制和仿真语言多采用宏汇编语言。因而,这样不可避免的会遇到运算精度问题,尤其是在定点乘法运算中,如果字长不够,则会导致仿真或控制系统的失真或达不到要求。本文结合一具体实时仿真系统讨论这个问题。更多还原

【Abstract】 In this paper,the accuracy of the real-time simulation based on IBM-PC micro- computer is analyzed.The accuracy problem in the real-time simulation and control arises when as- sembly language is used in fixed pint multiplication.It will lead to failure or unsatisfaction if the word length is not long enough.A suggestion for this problem,a hydroturbine real-time simulation system,is devoleped.更多还原
