Design of PID controller of ball-beam system
Abstract:Ball and beam system, which has a series of advantages such as the mechanical structure is simple, compact structure, high safety , is widely concerned and adopted in high-tech areas. For exapmle, in the field of biology, medicine, ecology , economic , social and other high-tech background . with the development of the automatic control system, it can reflect the robustness in the control process and many of the key problems.the Ball and beam system systems is become more and more important.
This dissertation, based on the linear inverted Pendulum of Googol ComPany,In PID control for the principle. Using Matlab software for real-time control system for the Ball and beam system PID controller design , drawing the appropriate conclusions.Firstly, in the analysis of system structure and working principle of the club , based on the use of electricity, Newtonian mechanics, the mathematical model of the system to establish the club , the club obtained the transfer function of the system and use it as an object , carried out in Simulink model structures .Secondly, making the P, I, D control as principle, analyze the stability of Ball and beam systems,then design of the incremental PID controller PID control subjects through different parameters on the dynamic response waveform cue analysis, carried out control the tuning, drawn , and the relationship between , and .Finally, analyzing the Ball and beam system performance by Simulink of real-time control of PID controller .
