Crushing and screening processes for aggregates are purpose-designed processes for producing aggregate fractions with pre-specified quality specifications. An aggregate production plant, crushing station, basically involves crushers in series for cru

Two decades ago, a predictive PI controller was introduced for regulation of dead time dominated linear time-invariant first-order processes. The introduction involved a simple tuning rule with consideration on easy implementation and good performanc

PID controllers are indisputably the most common controller type encountered in process control applications. Therefore, they have been quite well accepted for process control of crushing processes as well. However, successful tuning of a PID control

A mechanism for automatic update of tracking simulator parameters is suggested. A tracking simulator is a simulator, which runs in real time, and which corrects its own behavior (models) by comparing real process measurements to simulator outputs. Ty

Mobile aggregate crushers operate with wireless communication for plant-wide operability, controls and monitoring. Mobile crushing plants typically have relatively long material transportation delays making processes rather dead time dominant. Conseq

Industrial processes are typically regulated by PID controllers. However, for dead time dominating systems, the PID controller is not very applicable. Several modifications of a PID controller have been presented among years for improving control per

A predictive PI controller is a simple but elegant reincarnation of a Smith predictor for low-order linear time-invariant processes with long dead times. Initially, the PPI was introduced for first-order plus dead time processes but it equally applie

This paper presents a method for tuning a setpoint weighted PI controller. Use of the setpoint weight provides freedom to decouple load disturbance and setpoint response design. The method proposed here is based on assigning the maximum absolute valu
