With the rapid development of science and economy, people have accelerated the utilization and exploration of marine resources, and a large number of unmanned sailboats at sea have emerged. Aiming at the problem of automation sailboat scientific research, this paper designs an intelligent sailboat device based on pid algorithm, with the single chip MK60 DN series as the control core. At the same time, this paper improves the traditional pid algorithm so that in the process of intelligent sailboat, automatic adjustment and feedback compensation of sailboat angle can be realized when wind force changes, so as to realize accurate closed-loop control of sail boat angle and ensure correct navigation. According to experiment results, the proposed system has been proved to be effective with the characteristics of high measuring precision, high sensitivity and high stability after being modified.

According to the specifications of a 20 kg load for the casting barrel, we have crafted a three-dimensional model of the robot and scrutinized the three phases of liquid level variation within the casting barrel throughout the casting procedure. Following our analysis, it has been ascertained that the relationship between time and angle is an implicit function, rendering the discovery of an analytical expression for time in terms of angle unattainable. The dynamics of the casting barrel have been emulated using MATLAB, revealing the presence of critical points in the function plot. Upon fitting the original function with a fifth-degree polynomial interpolation, the resultant fifth-degree polynomial function depicting time against angular acceleration exhibits significant oscillations, particularly at the critical points. To address this, a proportional integral derivative algorithm, predicated on the discretization of time and acceleration functions, has been implemented for rectification. The outcomes demonstrate that this approach effectively diminishes the oscillation amplitude of the function plot and enhances its alignment with the original function.

Course control is one of the key research points for intelligent navigation of ships. Based on the optimization characteristics of Beetle Swarm Optimization (BSO) algorithm, this paper designs a ship course online self-optimization controller. Firstly, the ship MMG model is established, and the rudder turning rate constraint is introduced to establish the course control objective function. Then, based on the PSO algorithm, the BAS algorithm is improved to the BSO algorithm, and the BSO-pid algorithm is used for online course control. Through a series of simulation experiments, it shows that the method of self-optimizing pid parameters by BSO algorithm has better control effect on ship course control. Furthermore, it lays the foundation for further research in combination with other algorithms.

The paper shows how closed-loop control procedure, using the algorithm Proportional Integrative derivative (pid) was applied to improve the photo and video cameras stability correction in real time. The stability system contains an Attitude Heading reference System (AHRS) sensor that is connected to a microcontroller that will make the operations for measuring angles of rotation (roll, pitch and yaw) acquired from a camera displaced on a suspended cable. Closed loop pid algorithm applied to stabilize the system was implemented as programming subroutines dedicated to Atmega162 microcontroller, at which they were recorded and processed in real time as input signals sensor information measured by the AHRS system. Programming based on a closed loop process control through actuators ordered 3 servo-motors for real-time correction of camera rotation angles. In this way it could be provided the positioning cameras error compensation, the errors being caused by different perturbing external factors. The adopted solution has achieved a cost reduction necessary to stabilize the cameras placed in mobile systems. The solution ensures also to increase the stabilization efficiency reported to the case of human operator intervention.

This project is to make a multifunctional wheelchair bed which is easy to use at home, aiming at reducing the labor intensity of nurses and improving the quality of life of the elderly or bedridden patients. The back of wheelchair can lift 0-80 degrees under the action of electric push rod. At present, the products on the market can only realize the uniform rotation of the motor without considering the sense of oppression caused by the transformation process. Based on this project, the force analysis of the wheelchair backrest under different motor speed is studied. The flexible film pressure sensor is added to collect the pressure data in the process of position and attitude transformation, and the speed of the motor is controlled by pid, so that the backrest is subjected to the process of position and attitude transformation. More uniform force makes the user's body posture change more intelligent and improves comfort
