In order to correct the error caused by dynamic characteristics of sensor in test system, a dynamic compensation method based on Quantum-behaved Particle Swarm Optimization is presented. With this method the structure and parameters of the compensator is optimized using QPSO algorithm according to the input and output of the sensor. To realize real-time correction for sensor's dynamic error, a data acquisition system is designed. In this design, the TMS320F2812 DSP acts as the main control chip. The optimized compensator is realized in system software by using the method of linear buffer and dual operation address with moving bits. Then the simulator of sensor is designed and its output is sampled by the system. The sampled data from system show that the system not only samples and stores data accurately, but also corrects the dynamic errors caused by simulator of sensor. Source
