关于客户
本案例研究中的客户是 Kappa Electronics，一家专门从事电机控制系统的咨询公司。凭借 70 多年的累积经验和深厚的行业背景，Kappa 为能够解决复杂问题并提供卓越的客户服务而感到自豪。他们对待每个项目的目标都是以比以前任何人都更好、更聪明的方式做事。在这个特定的项目中，他们的任务是为新的无人机设计开发强大的电机控制系统。
挑战
Kappa Electronics 是一家专门从事电机控制系统的咨询公司，一位客户寻求帮助控制新无人机设计的电机。面临的挑战是为无人机应用开发强大的电机控制系统。控制系统需要能够处理 40 赫兹到 2000 赫兹的电机频率，并在各种扭矩和参数变化下表现良好。出于成本和重量的考虑，排除了使用轴传感器来获取转子磁通相对于定子框架的角度。由于需要确保无人机在任何条件下都不会从天上掉下来，这一挑战变得更加复杂。
解决方案
Kappa Electronics 选择 Altair 的 SolidThinking Embed® 软件来协助他们开发电机控制系统。该软件是基于模型的嵌入式系统开发的可视化环境，提供快速仿真速度、快速图表编辑、深度数据输入、2D 和 3D 绘图功能。这使得 Kappa 能够快速开发动态系统的虚拟原型、改变参数并验证系统性能。 Kappa 开发了一种观测器，通过测量电机的电压和电流来估计磁通角。他们还设计了一种多模式观察器结构，可以根据操作条件动态地重新配置自身。 Kappa 使用 Embed 的文件输出功能生成了 600 多个特征数据图，这些数据表明角度误差较低，并表明观察者即使在非常不利的条件下也不会失去角度锁定。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Remote Temperature Monitoring of Perishable Goods Saves Money
RMONI was facing temperature monitoring challenges in a cold chain business. A cold chain must be established and maintained to ensure goods have been properly refrigerated during every step of the process, making temperature monitoring a critical business function. Manual registration practice can be very costly, labor intensive and prone to mistakes.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.

Premium Appliance Producer Innovates with Internet of Everything
Sub-Zero faced the largest product launch in the company’s history:It wanted to launch 60 new products as scheduled while simultaneously opening a new “greenfield” production facility, yet still adhering to stringent quality requirements and manage issues from new supply-chain partners. A the same time, it wanted to increase staff productivity time and collaboration while reducing travel and costs.
