| Popis: | 96 This thesis studies the design of a control chip for realizing the vector control laws of an induction servo motor using cell-based IC design flow. The induction motor vector control laws are first per unitized so as to be applicable to various motor ratings. Then MATLAB/Simulink programs are developed to establish the vector controlled induction motor models in floating-point formats. To design both 32-bit and 16-bit models in fixed-point formats, the Q values are determined by predetermined motor operating points. The hardware description language Verilog is used to code the digitalized vector-control laws and the motor model. The design starts from the basic computation units such as multiplier, integrator and divider. It then follows by more complicated modules such as the PI controllers, slip estimators, voltage decouplers, and the I/O interface and registers for the desired control chip. The complete vector-controlled chip modules are ultimately integrated and the RTL (register transfer level) circuit diagram is synthesized. Both the MATLAB/Simulink and Verilog models are simulated and compared. The simulation results confirm the accuracy of the proposed approach. The final step is to complete the chip design flow and the thesis successfully complete routing and layout for both the 32-bit and 16-bit vector-controlled chips. |
