Programmable Power Controller Scheduler for Event-Driven Cycle Control

The control module is segmented into distinct functional components: a scheduler unit that manages event-driven task scheduling, a processor that executes control algorithms, and an interface unit that handles power train events. This segmentation enables programmability through modular software threads while keeping each hardware component relatively simple and cost-effective to manufacture.

The processor is designed as a universal computing element capable of executing multiple different control algorithms through programmable threads. Rather than requiring separate dedicated hardware for each control function, a single processor can adapt to different power train control requirements by loading appropriate software threads, thereby achieving multi-functionality without proportionally increasing device complexity.

The scheduler unit performs preliminary action by pre-processing power train events and preparing control tasks before they reach the processor. Events are captured and organized in advance, allowing the processor to execute control algorithms with deterministic timing rather than experiencing unpredictable interrupt latency, thus ensuring real-time response capability.

The scheduler unit acts as an intermediary between the power train events and the processor. It buffers and manages the flow of events, translating raw power train signals into structured control tasks that the processor can handle efficiently. This intermediary layer isolates the processor from direct event interrupts, enabling reliable real-time control while maintaining programmability.

The control system operates on periodic switching cycles with predetermined timing. The scheduler and processor are synchronized to the power train switching frequency, executing control algorithms at regular intervals rather than requiring continuous nanosecond-level interrupt response. This periodic action achieves effective cycle-by-cycle control while using simpler, more cost-effective hardware compared to continuous high-speed response systems.

The control module incorporates self-service mechanisms where the scheduler automatically manages task prioritization and timing without external intervention. The system self-regulates its own execution schedule based on incoming events, reducing the need for complex external control circuitry and high-speed interfaces, thereby achieving fast response times with reduced device complexity.
