本文讨论了计算机(?)控多台双输入双输出电加热炉恒温过程的多变量自校正调节器。首先讨论了多变量系统最小方差控制律和自校正调节时多变量系统参数在线估计的的递推算法,然后离线建立电加热炉的数学模型.运用上述算法计算了最小方差控制律,仿真结果示明了该算法参数的收敛性。自校正调节器实时群控结果表明;自校正调节器具有较高的适应能力,它能跟踪参数的变化,实际控温效果优于 PID 调节器和LQG 控制器,具有较高的控制精度。本多变量自校正调节器采用国产 JS-10A 小型机。
This paper discusses the computer (?) Control multiple dual-input dual-output electric furnace thermostat multivariable self-tuning regulator. Firstly, the recursive algorithm of multivariable minimum variance control law and on-line estimation of multivariable system parameters for self-tuning and adjustment was discussed, and then the mathematical model of electric heating furnace was established offline. The minimum variance control law was calculated by the above algorithm. Obviously, the convergence of the algorithm parameters. Self-tuning regulator real-time group control results show that; self-tuning regulator has a high adaptability, it can track changes in parameters, the actual temperature control effect is better than the PID regulator and LQG controller, with high control accuracy. The multivariable self-tuning regulator using domestic JS-10A minicomputer.
