摘　　要：针对新型数字液压驱动系统这一类非线性、时变的动力学系统,本文利用模糊算法的强鲁棒性以及根据人类免疫系统而设计的免疫算法优良全局寻优能力,提出了模糊免疫PID控制方法。这种控制方法不需要建立控制对象精确的数学模型,是一种具有鲁棒性强、实时性强的智能控制方法。计算机的仿真实验证明,在模糊免疫PID控制器的控制下,新型数字液压驱动系统具有了高响应速度、无超调和自适应能力强等新特征。Aiming at the new digital hydraulic driven system, which is a strong non-linear and time-varying system, this paper utilizes the strong robustness of fuzzy algorithm and the global optimization of the immune algorithm designed according to the human immune system. A new fuzzy immune PID control method is proposed. This controlling method does not need to establish the controlled object＇s accurate mathematical model. And it is a kind of intelligence control method with strong robustness and fine timeliness. The computer simulation proved that, in under the fuzzy immune PID controller controlled, the new digital hydraulic driven system has many new characteristics such as high-speed response, no overshoot, and strong adaptive ability and so on.
