基于DSP的电线加塑恒张力模糊变结构控制系统的设计

The design for tension fuzzy variable-structure control system of electric cable plastic wrapping process based on DSP

针对电线加塑生产过程中张力系统中存在的加塑不均匀、铜芯易被拉断或堆挤等问题,提出利用数字信号处理器(DSP)对张力进行控制的方案。硬件设计以美国TI公司生产的TMS320LF2407A DSP芯片为主控单元,软件设计是利用DSP集成开发环境CCS 2.2,采用C语言和汇编语言混合编译的方法进行控制程序的开发,在控制策略上采用模糊变结构控制。

According to the problem such as plastic wrapping nonuniform, copper proning to pull and break or clump and squeeze etc. of tension control system for electric cable plastic wrapping process, this paper presents a method of tension control in the system of electric cable plastic wrapping process using DSP. The design of hardware use TMS320LF2407A DSP as the main unit and use corresponding peripheral device as subsidiariness; the design of software uses C language and assembler language hybrid method to control the development process which in CCS 2.2 intergration development environment, fuzzy variable-structure control algorithm is applied.
