The system uses C language as a design language. and the keil is used as the development environment,and the STM32 library function version of the embedded application development and the STAG emulator are used to the core chip and then debug. The results show that the design can fully realize the function of highly intelligent animals aquarium.展开更多

The scheme is using gyroscope and accelerometer to measure angle and angular velocity of vehicle,and the vehicle speed is obtained through the hole, encoder, using Kalman filter algorithm and PID control to realize the balance between two rounds of car. The balance control results of actual operation show that the balance of the car stable system design can be upright and can realize turn forward motion etc.展开更多

The superelastic hoses are sealed at their both ends. The breakdown condition of that is taken as the object of study under different combined and working conditions. The upper computer of the experimental bench adopts MCGS configuration software. The test of experiment can meet the control and real-time monitoring of experimental platform conditions. In the experiment,we measure and monitor the data of temperature,tensile force,pressure and so on by the analog modules. During the process of experiment,the actuators like the solenoid valve and the motor are controlled by the switch. The paper describes that the constitution of experimental control system of the superelastic hose instability, control function and the achievement of monitoring condition. It is convenient to operate in the control system,the design cost is low,the man-machine interface is simple and understandable,and the experimental control system will be significant in bio-engineering and medical research.展开更多
