DSP-Based Control System for Dual Controller Environment

摘要:

以TMS320F2812为微处理器,设计了一种双控制器高精度环境控制系统。依据上位机设定部位的温湿度指标与系统采集的温度、湿度信号,利用DSP内部集成的模数转换器进行处理,并经过双控制器算法来控制PWM输出,从而使受控对象能够更快,更精确地达到设定温度,仿真结果表明,双控制器控制输出稳定、调节速度快、能够获得良好的鲁棒性。

Abstract:

TMS320F2812 microprocessor is used to design a DSP-based high-precision environmental control systems dual controller. ADC was integrated within DSP processes the collect temperature, humidity signal and dual controller algorithm controls the PWM output, so that the controlled object could be faster and more accurate to set temperature. Simulation obtains two controller output stability, regulation faster, and getting a good robustness.
