本文提出一种适用于微型计算机控制系统的自适应控制规律算法。该法包括对系统的相关识别,品质指标(I、R、A、R)的计算及根据品质指标与期望值之差对调节器的参数(P、I、D)进行自整定等内容。本课题还研制了A/D,D/A转换过程通道,将单板机与小型模拟机联成一个数字模拟仿真系统。并且编制了实施上述自适应算法的一系列实时控制程序。仿真实验证明,对特性经常变动的过程对象,采用这种控制方案,能够保持系统始终处于予先设定的最佳性能指标状态下运行。 This paper presents a kind of adaptive control law algorithm suitable for microcomputer control system. This method includes the calculation of the system related identification, quality indicators (I, R, A, R) and the self-tuning of the parameters (P, I, D) of the regulator according to the difference between the quality indicator and the expected value. The subject also developed A / D, D / A conversion process channel, the single board machine with a small analog machine into a digital simulation system. And compiled a series of real-time control programs to implement the above adaptive algorithm. Simulation results show that for the process object with frequent changes in characteristics, this control scheme can be used to keep the system running under the preset optimal performance index.
