“…This results in frequent lightpath establishments and increases the number of processes of the control packet. On the other hand, I‐PD control can avoid the significant increase of the output from the proportional and derivative elements [11–14]. As a result, it is expected that frequent lightpath establishment processes can be avoided by using our proposed method.…”

This paper proposes a task transmission control with dynamic lightpath setup in an optical grid. In our proposed method, a job manager changes the number of tasks in a resource manager dynamically so as to maintain a constant processing delay. It leads to effective utilization of computing resource. I-PD control is applied to maintain efficient network management. Furthermore, in order to avoid frequent lightpath setup process, multiple lightpaths are established simultaneously by our proposed algorithm. Numerical results show the effectiveness of the proposed task transmission method.

An equilibrium control structure for boiler-turbine units is presented in this paper to restrict the exceeding change of steam pressure. The central component of this structure is named as "Steam Pressure Equilibrium Controller", which is composed with two parts: the pressure error compensator and the pressure set-point optimizer. The former is designed to regulate the change rate and directions of load demand under certain rules according to the steam pressure error. The latter is designed to change the set-point of steam pressure in a reasonable range if the aberrance of steam pressure is serious. Simulation results show that the proposed control structure has good performance for pressure error control.
