摘　　要：为在设计全过程中能对打印机字车系统的运动及控制系统的性能进行验证,从而设计出性能优异的字车系统,加快设计进程,在Adams中建立了字车机构的虚拟样机,在Simulink中建立控制模型,应用Adams/Controls插件联合Adams和Matlab对字车机构进行机构运动和控制的协同仿真。对字车机构的速度控制采用模糊PID控制方法,应用Matlab模糊逻辑工具箱建立模糊PID控制器,利用模糊控制规则在运行的过程中动态地改变PID控制参数。结果表明,应用模糊PID控制可以达到很好的控制效果,展示了对复杂机电一体化系统进行联合仿真的一般方法。The wide-format inkjet printer requires the speed of the print carriage remained stable in the printing process. To verify the mechanical and control systems＇ performance of the print carriage at the whole design process, the paper designed a print carriage system with excellent features so as to speed up the design process. In the paper, it established a virtual prototype of the print carriage mechanism in Adams, and constructed the control system model in Simulink, by means of the package of Adams / Controls to joint Adams and Matlab it system for mechanism of kinematics and dynamics. made the simulation in performance of the control The speed control of print carriage adopted fuzzy PID control method. By use of fuzzy logic toolbox in Matlab, it built the fuzzy PID controller, and through the fuzzy control rules it could change the parameter of PID controller while running. Simula- tion results show that the application of fuzzy PID control method can achieve the desired effect, and it shows a general method of the co-simulation for complex mechatronic system.
