【摘要】 针对多温区电加热炉温度控制系统存在强耦合和纯滞后的特点,采用前置反馈补偿解耦控制法,将多变量耦合系统转化成单变量独立控制系统,并用Smith预估补偿器对解耦后的系统进行延迟补偿,仿真结果表明解耦效果令人满意,滞后环节得到了补偿,并且整个系统的抗干扰性能得到了提高,从而证明了方法的有效性。更多还原

【Abstract】 According to the characteristics of strong couple and pure lag in control system with multi-temperature zones, the preposition feedback compensation decoupling control method is employed to convert the multivariable and couple system to single variable independent control system, and adopt Smith predictor to carry out the lagging-time compensation for decoupled system. The result suggests that this decoupling method is effective, the time-lagging part has been compensated, and the capability of anti-jamming is improved. It approves that the method is valid.更多还原
