Research On The Bearings Running-system Of The Solar Panels Drive Mechanism Based-on The Fuzzy PID Control Algorithm

For solar panels drive mechanism bearings running-system, it is a complex system ofnonlinear, multivariable, severe instability. Typical traditional mathematical analysis of thecontrol algorithm structure is difficult to be expressed and dealt with, if you want to model thiscomplex system, on idealized assumptions and deal with the need to establish the mathematicalmodel: the nonlinear of linear, change is constant, the distribution of the parameters into lumpedparameter. In this case, a single conventional control algorithm can not make solar panels drivemechanism bearings to run together the system has good dynamic and static characteristics of thenew control algorithm is proposed and studied. Based on fuzzy PID control algorithm acting onthe bearing to run together on a system of solar panels drive mechanism, allowing the system toobtain a good dynamic and static characteristics. The research on the solar panels drivemechanism bearing system and the corresponding field of the running-in of great significance.Grasp the basic principles of solar panels drive mechanism bearing the running-in system basedon the realization of permanent magnet DC torque motor for the system and system hardwaresoftware, have carried out a preliminary study. The detailed contents are as follows:(1) Bearing drive mechanism by studying the solar panels to run together the basic principles ofa preliminary study on the system used by the permanent magnet DC torque motor, and establishits mathematical model on the basis of further analysis its speed steady.(2) Proposed optimal control algorithm used in solar panels drive mechanism bearingsrunning-system-fuzzy PID control algorithm. This algorithm steady speed drive mechanism ofsolar panels bearing the running-in system has played a good role. At the same time design thefuzzy PID controller.(3) The drive mechanism of the solar panels bearing the running-in system hardware andsoftware design and preliminary study, including: DSP control module, the angle measuringsystem and power driver and load guidance system. The hardware circuit design and softwareprograms designed for solar panels drive mechanism bearing the running-in system has goodspeed steady and improve static and dynamic characteristics have a strong support.(4) Bearing run together on a system of solar panels drive mechanism, the use of fuzzy PIDcontrol algorithm and preliminary experimental studies have shown that. Experimental resultsshow that the fuzzy PID control algorithm with PID control algorithm and fuzzy controlalgorithm is compared, with the characteristics of the overshoot is reduced and the rate of steadyimprovement.
