A hardware-in-the-loop simulation system for the mixed separation process

A representative hardware-in-the-loop simulation system was established for the mixed separation process to meet the demands of industrial process control technologies with complex characteristics. A hardware-in-the-loop simulation system was devel-oped composed of a virtual object computer, a controller-design computer, a monitoring computer, virtual actuators, virtual detecting instruments, and a control system to achieve mixed separation. The control algorithm of the system was based on actual industrial soft-ware, and Matlab was use to design the virtual object, virtual actuators, virtual detecting instruments, and online identification sys-tem. The mechanism modeling of controlled object, parameter identification of controller design model, controller design and controller performance evaluation were completed on the virtual object computer, controller-design computer and monitoring computer. The pro-posed system lays the foundation for future industrial applications of control algorithms for complex industrial processes.
