面向汽车集成式电子液压制动系统需求，设计一种鲁棒性液压力控制系统。基于系统特性分析发现，集成式电子液压制动系统为非线性时变系统，其工作受到温度、湿度、载荷扰动等多重不确定因素的影响，容易产生振荡的现象。因此要求液压力控制系统对外界不确定的扰动有较强的适应性，同时满足指标要求。利用基于系统改进的田口方法，提出一种集成式电子液压制动系统鲁棒性液压力控制方法。建立相关试验平台并利用该方法实现液压力鲁棒性控制。试验结果表明，所设计的鲁棒性液压力控制方法鲁棒性强，响应迅速，在500次试验内均保持稳健。因此，研究为非线性时变控制系统设计找到了一个新的设计方法，运用该方法设计出的控制系统可以使系统的输出对于干扰不敏感，在提高系统的鲁棒性的同时，优化系统性能。

A robustness control system is presented to fulfill the requirements of hydraulic pressure control of integrated-electro- hydraulic brake system. Based on the analysis of chararistics of system it is found that integrated-electro-hydraulic brake system is a nonlinear time-varying system. It is affected by ambient temperature, humidity, load disturbance and other uncertain factors and oscillation occurs. In order to solve these problems the control system of I-EHB is required to have a good adaptation for external uncertain disturbance. Using Taguchi method which is modified according to the system a robustness hydraulic pressure control system for integrated-electro-hydraulic brake system is formed. Using the test rig this robustness control system is tested. Results show that this robustness control system responded rapidly and has a good robustness. In 500 experiments the system keeps in stability. Hence a new method for the control system design of nonlinear time-varying system is found. By using this method the output of system is insensitive to external disturbance, the robustness of system is improved and the performance of system is optimized.
