【摘要】 针对某军工企业橡胶硫化系统控制精度低、次品率较高、自动化集成度低等问题,根据罐式硫化机在对实心轮胎硫化的过程中,控制对象的非线性、时变和纯滞后等特点,设计了一种高精度罐式硫化机橡胶硫化控制系统。系统以TMS320F2812为主控制器进行开发,设计了相应的外围电路,并采用等效硫化方式取代定时硫化方式,控制算法采用传统数字PID和模糊控制相结合的方式,并引入Smith预估器来实现对滞后特性的动态补偿,设计了带Smith预估补偿的自适应模糊PID控制算法。实践证明,本系统在稳定自动运行的基础上,很好的满足了军品橡胶对温度的高精度控制要求,且成本低、操作简单,提高了企业的经济效益。更多还原

【Abstract】 To solve the problems of low control accuracy,high defect rate and low degree of automation integration of solid tire curing system in a military industry enterprise the high accuracy solid tire curing system,which is based on the characteristics of nonlinear property,time-varying and pure hysteresis of control object in the solid tire curing process of pot-type vulcanization machine,is designed,The system selects TMS320F2812 as the main controller to devise,and the corresponding peripheral circuits.Besides the system also adopts the equivalent curing mode instead of the previous timing curing mode and designs adaptive Fuzzy PID control algorithm with smith proforma compensation combining the advantages of digital PID and fuzzy control theory and introducing smith predictor to dynamically compensate for it’s dynamic performance.The practice showed that the control system can not only run steady,but also well meet the high accuracy control requirements to temperature.Besides,the system has the characters of low cost,easy to operate,and the economic benefit is greatly improved.更多还原
