传统程控电流源的设计大部分都是采用PID算法控制的,PID控制器由于其具有原理简单、稳定可靠、无静差等优点,在过程控制中得到广泛应用,是较经典成熟的控制器.但它对具有非线性因素和不确定性等特征的系统很难达到预期效果.在设计上采用了先进的控制算法,采用模糊算法与PID算法结合的Fuzzy-PID控制,通过仿真得到了很好控制效果.%Traditional program-controlled current source is controlled based on the PID control algorithm, this controller is a classic and sophisticated controller and widely used in process control because of its simple principle, reliable and zero steady-state error performance. But it is difficult to achieve the desired results in the system with non-linear and uncertainty characteristics. This article uses advanced control algorithms which combine Fuzzy arithmetic with PID arithmetic, and it has a high control precision throng simulation.
