【摘要】 根据闭环控制系统的输入、输出数据,应用LJ直接搜索的最优化方法来估计对象特性的参数,并以此为基础,继续用LJ法确定调节器的最优整定参数,这是一种行之有效的好方法,它能方便地找到同时适应负荷与给定值变化的折衷最优整定参数的新途径。首次解决了目前用一般方法所未能解决的问题。它的输入不仅是阶跃信号,而且可以是包括伪随机信号在内的任何信号,从而大大提高了对实际生产过程的适应性。计算机仿真的实例表明用这种方法可以取得较为满意的效果。更多还原

【Abstract】 According to input and output of a closed loop control system, the parameters of the process model can be determined by optimization method of LS direct search procedure, whereby propriety of controller adjustments can be made. It might be an efficient and novel approach that yields a compromise for controller adjustments in both setpoint and load changes. Input to the system can not only be a unit step but other kinds of signals as well; e.g., prbs. Computer simulations demonstrated feasibility.更多还原
