Real-Time System Controls: Implementing Low-Latency Applications and Industrial Automation on Linux

Transform Linux into a Precision Real-Time Controller for Industrial Automation Are you ready to harness the full power of Linux for mission-critical industrial control systems? This comprehensive guide takes you from fundamental concepts to production-ready implementations of deterministic, low-latency automation controllers. Master the Complete Real-Time Linux Stack This book provides everything you need to build hard real-time systems capable of sub-millisecond response times. You'll learn to configure PREEMPT_RT patches, optimize kernel scheduling, isolate CPU cores, and eliminate latency sources that plague standard Linux deployments. What You Will Learn Learn architectural fundamentals of deterministic systems and why standard Linux fails at real-time tasks. Discover how to compile and configure real-time kernels with PREEMPT_RT patches for microsecond-level precision. Master CPU isolation techniques, memory locking strategies, and BIOS tuning to achieve consistent performance. Implement real-time applications using POSIX APIs with SCHED_FIFO, SCHED_RR, and SCHED_DEADLINE policies. Build lock-free inter-process communication systems that eliminate jitter. Deploy industrial networking protocols including EtherCAT, Modbus, and CAN bus. Practical Implementation Focus Every chapter includes production-ready C and C++ code examples designed for real-world deployment. You'll implement PID control algorithms, fault-tolerant architectures, and comprehensive debugging strategies using Ftrace and KernelShark. Industrial Applications Covered Motion control systems running at 1kHz to 10kHz update rates, high-speed data acquisition from sensors and ADCs, protocol gateways bridging legacy industrial buses with modern Ethernet, and Industry 4.0 smart factory implementations. Advanced Topics Include System optimization for deterministic performance, advanced debugging and latency tracing techniques, security hardening for industrial environments, and deployment strategies for production systems. Who This Book Is For This guide is essential for embedded systems engineers transitioning to real-time Linux, industrial automation programmers seeking deterministic performance, robotics developers requiring precision timing, and systems architects designing IoT edge controllers. Stop compromising between the flexibility of Linux and the determinism of proprietary RTOS. Build professional-grade real-time controllers using open-source technology.
