It is important for conventional thermal power units to participate in frequency adjustment and peak regulation for the safe operation of grid side. This paper research on coordinated control system (CCS) for boiler-turbine units based on fractional-order control (FOC). The realization of fractional-order PID (FOPID) controller in distributed control system (DCS) is provided. The engineering application results show that this algorithm is easy to be realized in project by applying all sorts of existing algorithms in DCS. Furthermore, this algorithm can overcome the large lag and inertia for boiler and improve the primary frequency and automatic generation control (AGC) tracking performance in boiler-turbine CCS effectively.

The paper proposes a novel learning-based coordination strategy for lateral control systems of automated vehicles. The motivation of the research is to improve the performance level of the coordinated system compared to the conventional model-based reconfigurable solutions. During vehicle maneuvers, the coordinated control system provides torque vectoring and front-wheel steering angle in order to guarantee the various lateral dynamical performances. The performance specifications are guaranteed on two levels, i.e., primary performances are guaranteed by Linear Parameter Varying (LPV) controllers, while secondary performances (e.g., economy and comfort) are maintained by a reinforcement-learning-based (RL) controller. The coordination of the control systems is carried out by a supervisor. The effectiveness of the proposed coordinated control system is illustrated through high velocity vehicle maneuvers.
