Now, PID controller is the most widely used controller in the world and various industrial control fields because of its simple structure, easy principle and excellent robustness. The most important and most difficult to grasp of a PID controller is the determination of its three parameters: proportional, integral, and differential. The parameters need to be adjusted in real-time to ensure the stability of the overall system. This paper describes several common PID parameter auto-tuning methods, and explains its basic principles.

Cooperation or Cooperative behavior constrained between any two nodes or groups always result in constant scrutiny for reconfiguration. This continual reconfiguration creates a new modulus for expansion and thus detecting community structure can fundamentally become a problem of identifying groups and a leader in a network. In a network, the influencer is commonly termed as leader and the leader node is a node that has high attraction to increase, i.e., high degree of centrality. In this paper, we devised an efficient method to detect influencers in a network through cooperative and spread strategies. This dynamic strategy technique is used to detect subevents and anomalies through social and physical sensor data. This paper contributes toward a dynamic game theory approach for information maximization by maximizing the influence features over the network for higher information delivery over the dynamic network.

The Smart Distribution Grid concept is conceived as a means to optimize and to improve the reliability and operation of the electric distribution network. The numerous and different types of information generated and time synchronized at a distribution network by smart meters, coupled with a communication infrastructure and data base management system provide the means to generate useful control algorithms. Attaching the location of each smart meter at the distribution grid to the monitored data opens the door to numerous advanced applications. control applications lend themselves for logical stratifications unique to the intended targets of control. Demand response has a rippling effect all the way to generation and also to distribution assets performance. Distribution automation could be local to the distribution network served by a distribution substation. Fast transient phenomena, harmonics problems can be highly local, limited to a particular feeder or at customer premises. The data requirements for each of the control applications mentioned before can be quite different from each other and also depend greatly on the location at the network. This paper tries to illustrate how the physical behavior of the electric energy delivery system dictates the requirements for data generated by the sensing devices to design algorithms for Smart Distribution Grid control applications.

As the long transmission line, complex mechanism, poor performance of regulation and control and low sensitivity of mechanical let-off, so it can not meets the requirements of stable tension. Therefore, the let-off mechanical was improved. This paper takes let-off system of SAURER400 rapier loom as experimental subject, mathematical modeling to every parts of loom, and takes simulation and comparison. The simulation results show the improvement of mechanical can meet the basic requirements of weaving, and it indicates the works that done former are effective and correct.

We present a new technology for real-time walking of a humanoid robot. A humanoid robot necessitates achieving stabilization for real time walking since it has basic problems such as structural stability. In this paper, a robust control algorithm for stable walking is proposed based the ground reaction forces, which are measured using force sensors during walking, and the environmental conditions are estimated from these situation. From this information the robot selects the proper motion and overcomes ground irregularities effectively. In order to generate the proper angel of the joint. The performance of the proposed algorithm is verified by simulation and experiments for a 20-DOFs humanoid robot.

A gradated cardioresponsive Left Ventricular Assist Device (LVAD) control algorithm was developed in order to improve cardiac reverse remodeling in patients who suffer from late to end-stage heart failure. This algorithm was created to improve physician control of the LVAD as well as improve awareness of the patient's condition. The control algorithm was validated using a mock circulatory system and simulated LVAD.

It is studied the control algorithms of automatic train operation (ATO), which concerns many functions during the train's operation, such as efficiency, punctuality, energy-economizing, stop precision, comfort and so on. In addition, energy-economizing arithmetic uses the control mode which operates according to target speed and makes the best use of coasting, timing arithmetic uses heuristic arithmetic that adjusts target speeds. On the other hand, the operating conditions of the train's being punctual or behind the schedule are all simulated on the computer, and the results are compared with those from practical operation. It is an effective method for further studying of automatic train operation system.

With the development of the intelligent construction in China, the research on the control method of its environment temperature has become an important subject for the related research field. Based on the dynamic analysis of the room temperature and air-condition system, the serial control strategy is presented in this paper, in which the master loop concerns with the control of the room temperature, and the slave loop is the control of the parameter delivering wind. Through the deep analysis of its work performance, it is proved that the serial control strategy is better than the single loop control because it can decrease the dynamic gain of the second interference for the loop of the room temperature. In the end, its control algorithm, whose master loop is PID and slave loop is PI, is investigated, and the good control effects about decreasing the dynamic error and compressing response time are gained by an experiment.

This paper introduces the digital PFC control algorithm of the chip in detail, designs a novel, bridgeless PFC topology which has simple current sensing circuit and low EMI, and compares bridge-less PFC and conventional Boost PFC circuits. Experimental results verify that the bridgeless PFC has higher power factor and efficiency comparing with conventional Boost PFC. When the designed bridgeless PFC circuit's power is 1 000 W, the power factor is more than 0.98, the THD is less than 10%, the efficiency is more than 0.97, and the EMI test result is lower than standard.
