Abstract:To improve production quality and efficiency of synthetic diamond, a novel control system of cubic press has been developed based on ARM7TDMI(S3C44B0X). Two efficient methods were adopted to solve the problems of large zero drift and poor repeatability by software and hardware. The pressure boosting speed and control precision were improved by three motors coordinated control and a special circuit was proposed for temperature control. Furthermore, several measures were utilized to prevent the malfunction of system. Application results have indicated that this control system has the advantages of low zero drift, high control precision, good repeatability and reliability.
