We have made the process for combining controls with mechanical system simulation as simple as possible. It starts with an ADAMS model. Decide what your control inputs and sensor outputs are. Inputs can be forces or motions. Their function value is defined to be from an ADAMS variable. Outputs are any run-time measures or ADAMS variables you want. Either export this model directly to the control application, or create a file with all of the required information. Now within the control application, build up your control law and include the ADAMS block to include ADAMS and your model in the simulation. Now connect your inputs and outputs to your control system blocks, and simulate the combined mechanical and control system design. You will see ADAMS start from within the control application. Your model will be loaded and you will see it move interactively in response to your control commands! All of your ADAMS data is saved to the standard results, request, and output files. All of your controls data is saved as well. Now connect your inputs and outputs to your control system blocks, and simulate the combined mechanical and control system design. You will see ADAMS start from within the control application. Your model will be loaded and you will see it move interactively in response to your control commands! All of your ADAMS data is saved to the standard results, request, and output files. All of your controls data is saved as well. * 生产过程信息化 第一部分 企业信息化 目 录 2 1 生产过程信息化的内容 现代产品开发的特点 现代产品开发通常面向复杂产品 复杂产品是这样一类产品： 客户需求复杂 系统组成复杂 产品技术复杂 制造过程复杂 项目管理复杂 涉及的 子系统多 学科技术种类多 人员/工具多 与外界环境的交互关系复杂 典型复杂产品： 航天器、飞机、汽车、复杂机电产品等 复杂产品 1. 现代产品开发的特点 强调系统的观点---- 强调在系统的层次上模 拟产品的外观、功能和 在特定环境下的行为。 现代产品开发与传统产品开发相比，具有如下 新的特点： 1. 现代产品开发的特点 涉及产品全生命周期----可应用于产品开发的全生命周期，并随着产品生命周期的演进而不断丰富和完善； 生产 销售 使用 维护/服务 报废/回收 规划 设计/确认 制造 概念设计 1. 现代产品开发的特点 强调不同领域的虚拟化的协同设计。 1. 现代产品开发的特点 （1）系统组成复杂，往往是机械、控制、电子等多个不同学科领域子系统的综合组合体； （2）开发过程复杂，不仅包括时间纵轴上存在的先后设计活动，而且包括横轴上某一时刻并发的设计任务之间的互相影响
