Abstract: Switched reluctance motor(SRM)take on the merits such as simple structure,low一cost,flexible control,etc. Switched reluctance drives system (SRD)has the advantage that conventional AC or DC drives system may have not,accordingly, as a emerging technology,theory and application research for SRD need to be studied. This dissertation is focused on the theory of control design for SRM.
Firstly,This thesis analyzes APC and CCC control method of SRM and its convert circuit characteristics,and designed the control system based on 8098 chip. Then,the thesis analyzes the linear magnetic characteristics of SRM ,and established the model for SRM. SRM has higher precision and robustness compared with conventional method,while Possessing the rapid and simple characteristics. with regard to the converter of SRD system. the thesis firstly gives the study of the topology of converters that have the least main switches,and then lucubrates the single switch per phase converter with C-dump energy recovery circuit. The thesis analyzes the operation mode of the converter and gives the formula for estimation of the converter一related parameters. All these works guide the design for converter of SRD.
