A crab-like octopod robot is introduced in this paper. The body structure of the robot is simuliar with a real crab. Each leg has three jionts which are driven by servomotors. The control system is a distributed hierarchical system with a top layer as gait generator and a bottom layer as servomotor controller. The bottom layer has enght individual control units every of which can control three servomotors using PID control method. The sensor systerm is composed of force sensors mounted at the end of the leg and a inclinometer provides pitch and roll angles of the body.

Size Data

A coagulation process for water purification plants mainly uses feedforward control based on raw water quality and empirical data and requires operator's help. We developed a new floc sensor for measuring floc size in a flush mixer to be used for floc control. A control system using model predictive control was developed on the floc size data. A series of experiments was performed to confirm controllability of settled water quality by controlling flush mixer floc size. An automatic control with feedback from the coagulation process was evaluated as practical and reliable. Finally this new control method was applied for actual plant and evaluated as practical.

For L4 and above autonomous driving levels, the automatic control system has been redundantly designed, and a new steering control method based on brake has been proposed; a new dual-track model has been established through multiple driving tests. The axle part of the model was improved, the accuracy of the transfer function of the model was verified again through acceleration-slide tests; a controller based on interference measurement was designed on the basis of the model, and the relationships between the controller parameters was discussed. Through the linearization of the controller, the robustness of uncertain automobile parameters is discussed; the control scheme is tested and verified through group driving test, and the results prove that the accuracy and precision of the controller meet the requirements, the robustness stability is good. Moreover, the predicted value of the model fits well with the actual observation value, the proposal of this method provides a new idea for avoiding car out of control.

Electromagnetic actuator systems composed of an induction servo motor (ISM) drive system and a rice milling machine system have widely been used in agricultural applications. In order to achieve a finer control performance, a witty control system using a revised recurrent Jacobi polynomial neural network (RRJPNN) control and two remunerated controls with an altered bat search algorithm (ABSA) method is proposed to control electromagnetic actuator systems. The witty control system with finer learning capability can fulfill the RRJPNN control, which involves an attunement law, two remunerated controls, which have two evaluation laws, and a dominator control. Based on the Lyapunov stability principle, the attunement law in the RRJPNN control and two evaluation laws in the two remunerated controls are derived. Moreover, the ABSA method can acquire the adjustable learning rates to quicken convergence of weights. Finally, the proposed control method exhibits a finer control performance that is confirmed by experimental results.

This paper presented a new method based on the Fuzzy self - adaptive PID for BLDCM. This method overcomes some defects of the traditional PID control. Such as lower control precision and worse anti - jamming performance. It dynamic model of BLDCM was built, and then design method for TS fuzzy PID model is given, At last, it compared simulation results of PID control method with TS Fuzzy PID control method. The results show that the TS Fuzzy PID control method has more excellent dynamic antistatic performances, as well as anti-jamming performance. The experiment shows that TS fuzzy PID control has the stronger adaptability robustness and transplant.

At present, basketball training needs more scientific training methods and techniques. In order to obtain these training methods, it needs to acquisition training information in the process of basketball training. Therefore, in view of basketball training to establish information control system, research on basketball players training characteristics and the law of motion in the process of basketball training, using control theory method to carry out information processing and analysis, and then the use of scoring methods carry out the authority score evaluation on basketball trainings influencing factors, according to the weight values, these are obtained on the basis of the score, then to carry out add sum, finally to obtain the evaluation scores of basketball training information control system. And then according to the weight value, to undertake an analysis of the basketball training control process, the basketball training information control method is put forward. The analysis results show that information control system is mainly manifested in the basketball training information collection and transmission, training scheme decision of coaches decision system as well as the feedback of decision information, which will complete the whole system construction of basketball training information control.
