摘要
线性功率放大器可对其输出电压和电流进行比较理想的控制,因此在工业控制场合得到了广泛的应用。如可编程电压源、可编程电流源、音圈电机驱动、直线电机驱动等。线性功率放大器主要以功率运算放大器为基础,在性能上接近理想的运算放大器的同时具有较高的动态电压和动态电流范围,如果要进行驱动电流提升,也很容易实现。从放大器的模型设计、传递函数计算、系统性能分析和MATLAB仿真辨识来全面验证系统设计的指标性能,从而做出最佳系统设计。
The linear power amplifier can control an ideal state to output voltage and current,so it is widely used in industrial control area.Such as programming voltage source,programming current source,voice motor driver,linear motor driver,etc.The linear power amplifier is mainly based on the power operational amplifier,in performance close to the ideal operational amplifier model,with a high dynamic voltage and current range.It is easy to enhance driving current.In this paper,using the design of the amplifier model,the calculation of transfer function,system performance analysis,simulation and identification with MATLAB to fully verify system performance,and thus make the best system design.
