Real-Time Deployability for Enterprise Systems
Despite its advanced capabilities, the T3-FLC is designed for practical implementation on standard embedded platforms. Its computational burden, while higher than simpler controllers, remains well within the limits for real-time operation in industrial PWM rectifier applications. This ensures that advanced control benefits are accessible without requiring prohibitively expensive hardware upgrades.
Computational Burden & Real-Time Feasibility
Challenge: Advanced control algorithms often incur high computational costs, hindering real-time deployment in embedded systems with strict sampling period requirements (e.g., 50 µs for PWM rectifiers).
Solution (T3-FLC): The T3-FLC requires approximately 250-400 operations per sample, translating to an estimated execution time of ~25 µs on a typical 150 MHz embedded processor. Its parameter memory footprint is modest, around 3 kB.
Result: Although more demanding than PI (~2 µs) and T1-FLC (~10 µs), the T3-FLC's computational complexity is well within the 50 µs sampling budget. This makes the T3-FLC a practical and deployable solution for enterprise PWM rectifier control, balancing high performance with real-time operational constraints.
