Fast Development of Flexible Motor Control System with Model Based Design

Abstract:

In this paper, model based design was introduced for fast developing the flexible motor control system. Unification of synchronous and asynchronous motors was proposed as they have same control framework. Based on the combinatorial study of motor control system’s inputs, outputs and state variables, a flexible motor control system was established that for synchronous and asynchronous motors, variety of control algorithms can switch, expand to and combine with each other freely. Building the finite element model of the motor with Ansoft Maxwell, the parameters and the electromagnetic characteristics of the motor have been obtained by finite element analysis. With the PID parameter auto-tuning method, the result of the system simulation proves the correctness of the control algorithm. After continuous testing and validation, the simulation model was changed into fixed-point model according to the embedded processor. Combining underlying drive with automatic code generation, the software of the motor control system was achieved rapidly. A servo driver and a motor servo performance test-bed were designed to test the automatically generated code and control algorithm. The experimental results show that a flexible motor control system with good servo performance has been achieved rapidly with model based design.
