This paper presents the implementation of dynamic control of an automatic wheelchair. The control objective is to control the velocities of the left and right wheels to follow the desired velocity commands. The equations of motion of the wheelchair are derived. The proportional-integral-derivative (pid) control algorithm is applied by utilizing incremental encoders as the feedback of the velocities of both wheels. The analysis of the closed-loop system shows that the pid algorithm is applicable to control the velocities of the wheelchair. The pid parameters are tuned based upon the open-loop Ziegler-Nichols method. In the implementation, the control algorithm is modified by limiting the input rate to prevent the windup. The experimental results show that the effectiveness of the algorithm.

During the coal cutting process in mines, the drill stem is easy to be deflected in virtue of the complicated geological conditions. The deviation control of drill stems is of great significance for the production efficiency and service life of drill stems. Based on analyzing influence factors of the deflection of drills, this paper builds up a model to describe deflecting forces of the coal seam. Utilizing MPU6050, a three axis gyroscope, to get the deviation angles, an improved pid control algorithm is employed to guarantee directional drilling of the coal mining machine by applying electrohydraulic servo valves to rectify the deflective drill.

Research Journal of Applied Sciences, Engineering and Technology 2014年第12期7卷 2416-2420页

The object of this study is a kind of 3 kW small steam generator, which can recover waste heat through making use of 0.1̃0.3 MPa steam. This can exploit secondary energy efficiently. The electricity generated can be commonly used as factory lighting, heating, fan and emergency power supply. But the generation voltage of the existed steam turbine is instable, especially when the steam pressure and the load of the generator changes suddenly. This can pose a threat to electrical safety and greatly limit the market of small steam generator. In this study, pid control algorithm is used to control the amount of steam into the turbine of generator system. And the closed-loop control system can make a real-time feedback regulation to the steam, so that the generator voltage can be stable. The user's electrical safety requirements are satisfied as well. © Maxwell Scientific Organization, 2014.

pid-based search algorithm: A novel metaheuristic algorithm based on pid algorithm

引用

EXPERT SYSTEMS WITH APPLICATIONS 2023年第1期232卷

作者： Gao, Yuansheng Liaoning Tech Univ Coll Sci Fuxin 123000 Peoples R China

In this paper, a metaheuristic algorithm called pid-based search algorithm (PSA) is proposed for global optimization. The algorithm is based on an incremental pid algorithm that converges the entire population to an optimal state by continuously adjusting the system deviations. PSA is mathematically modeled and implemented to achieve optimization in a wide range of search spaces. PSA is used to solve CEC2017 benchmark test functions and six constrained problems. The optimization performance of PSA is verified by comparing it with seven metaheuristics proposed in recent years. The Kruskal-Wallis, Holm and Friedman tests verified the superiority of PSA in terms of statistical significance. The results show that PSA can be better balanced exploration and exploitation with strong optimization capability. Source codes of PSA are publicly available at https://*** ***/matlabcentral/fileexchange/131534-pid-based-search-algorithm.

Adaptive Self-Tuning pid algorithm Based on Continuous Synthesis

引用

IFAC Proceedings Volumes 1997年第21期30卷 481-486页

作者： Mikuláš Alexík University of Žilina dept. of Technical cybernetics Slovak republic

This paper describes the analytical pid algorithm which has the adaptive self-tuning performance. It’s synthesis is made in a continuous domain. This means that identification is followed by recalculation into the continuous domain and the final gain of the algorithm is compensated due to sampling interval. Simulation experiments performed on analogue models as hybrid simulation in real time are also shown. The suggested design of the control algorithm is robust against the changes of the plant parameters and change of sampling interval. The simplicity of the control algorithm makes it suitable for initial experiments with adaptive algorithms in the teaching process and also in real control of heat exchangers and energetic plants.
