Benchmarking Networked Control Systems

Abstract

Abstract-Smartification of devices and ever-increasing connectivity are major factors paving the way towards the creation of networked control systems (NCS). Traditionally, both domains involved in an NCS, network and control, are considered separately. Towards a novel methodology for benchmarking such systems, we propose a series of key performance indicators (KPIs) that are based on well-established foundations of both worlds. These KPIs form our framework for the development of an NCS benchmark. The majority of KPIs, particularly those from the network domain, are applicable to any type of NCS. We are currently implementing an evaluation platform based on Lego Mindstorms to demonstrate and apply our framework. Both the benchmarking framework and our platform are designed with high affordability and easy reproducibility in mind.We plan to release our source code and construction manuals to motivate others to recreate our benchmark.

NCSbench: Reproducible Benchmarking Platform for Networked Control Systems

“…III. In fact, we not only extend the existing methodologies [18], [19] The purpose of the benchmarking methodology is to define the necessary amount of information in order to reproduce and evaluate experimental results using the NCS platform. Following the ACM's reproducibility terminology [20], we first want to recreate our own results thereby establishing repeatability.…”

“…Although practical NCS implementations pose a major challenge in reproducing NCS experiments, there has been an attempt in the literature to define conceptual CPS benchmarking scenarios [15]- [19]. Nethi et al [15] present a platform for the emulation of NCS to enable their comparison in different scenarios.…”

“…The framework allows experiments with real NCS, but does not tackle the aspects of reproducibility and comparison. Boano et al [18] and Gallenmüller et al [19] elaborate on how to implement experimental benchmarks and define key performance indicators (KPIs) for the comparison of experimental results. Nonetheless, they do not conduct a practical study for the verification of the proposed methods in their own work.…”

“…Dimana komputer merupakan alat pengolah data yang sudah di tanamkan sebuah prosedur yang telah dirumuskan [9]. Komputer diciptakan dengan tujuan untuk melakukan perhitungan arimetika dan tanpa ada mesin pembantu [10]. Seiring perkemabngan sampai sekarang komputer sudah melalui berbagai tahapan seperti menghitung, mengetik, mendesain , editing video, monitoring tafik lalulintas jaringan dan masih banyak lagi kegunaan dari perangkat komuter.…”

Next Generation Resilient Cyber-Physical Systems

“…Although the term CPS emerged recently 1 , it builds upon very well-established research fields, i.e., embedded computing, control theory and human-computer interaction. For instance, a CPS can be easily modelled as a Networked-Control System (NCS) [24]. The major difference is that the controller is coupled with the actuators and sensors through a communication network (e.g, an Ethernet-like network).…”
