the PDD40***101 actual process control system, the system based on PID control technology accounts for more than 80%. The application of PID loop plays an important role in realizing the stable, efficient and high-quality operation of the device. All DCS manufacturers take this as a powerful competitive weight to seize the market and develop their own PID self-tuning software. In addition, according to the control function of DCS, based on the basic PID algorithm, various improved algorithms can be developed to meet the various needs of the actual industrial control field, such as PID control with dead zone, PID control with integral separation, PID control with differential first, PID control with incomplete differential, PID control with logic selection function, etc.Different from the traditional PID control, the predictive control algorithm based on nonparametric model predicts the state of the future output of the system through the predictive model, and uses the rolling optimization strategy to calculate the output of the current controller. According to different implementation schemes, there are various algorithms, such as PDD40***101 internal model control, model algorithm control, dynamic matrix control, etc. At present, practical predictive control algorithm has been introduced into DCS.
PDD40***101 For example, idcom control algorithm software package has been widely used in practical industrial processes such as hydrocracking, catalytic cracking, atmospheric distillation, naphtha catalytic reforming and so on. In addition, there are HPC of Honeywell, predictrol of Yokogawa, predictive controller based on Kalman filter developed by Shanwu Honeywell in tdc-3000lcn system, etc. This kind of predictive controller does not simply put the Kalman filter before the previous predictive control to filter the noise, but takes the Kalman filter as the optimal state estimator to speculate the optimal state and filter the noise at the same time.

There are many advanced control algorithms. At present, many control software companies and DCS manufacturers at home and abroad are competing to develop engineering software packages for advanced control and optimal control, hoping to embed advanced control and optimal control strategies in configuration software.
