Design of a Radioactive Source Sampler Based on CPAC
This paper puts forward a design project of sampler for solving the difficult problem of radioactive source sampled by manual work because of radioactive sources radioactivity. The project includes mechanical bodys design, controllers design, and controllers realization. According to mechanical bodys motion characteristics, advances an iterative learning algorithm of exponent variable-gain to design controller for the radioactive source sampler whose manipulator arm can follow the given tracks. The design can get satisfying track following control effect by computer simulation, and can content control demands of sampling process. On the realization of controller, applies Computer Programmable Automation Controller (CPAC) made in Googol Technology to sampler and gives its hardwares realization method. Now the prototype tested has already substituted for tester to finish automatic sampling process in accordance with sampling program set in advance.
Keywords: CPAC, motion controller, iterative learning, radioactive source sampler.
