Original abstract
This paper deals with a design of a electromechanical actuator (EMA) control system with advanced safety requirements. Based on the Failure Mode and Effects Analysis (FMEA), a redundant structure of sensors and electronic control units (ECUs) is proposed. Following the compromise between safety and simplicity, only two channels (sensors and ECUs) are used. A Voter (hardware which routes the output signals from ECUs to power electronics) is implemented on a complex programmable logic device (CPLD) using hardware description language (HDL). As a case study, the proposed system structure is implemented on a self-balancing vehicle control system. The Model Based Design (MBD) approach is applied during the system development and testing. ECUs are based on dsPIC Microchip devices and programmed using automatically generated C code.

Tento článek se zabývá návrhem na elektromechanického pohonu (EMA) řídicího systému s pokročilými bezpečnostními požadavky. Na FMEA (FMEA), redundantní struktura senzorů a elektronických řídicích jednotek (ECU), na bázi se navrhuje. Následovat kompromis mezi bezpečností a jednoduchostí, jsou použity pouze dva kanály (senzory a ECU). Volič (hardware, který směruje výstupní signály z ECU na výkonové elektroniky) je realizován na složitém programovatelného logického zařízení (CPLD) za použití programovacího jazyka (HDL). Jako případová studie, navrhovaná struktura systému je realizována na řídicím systému vozidla vlastním vyrovnávání. Indikátor (MBD) přístup Model Based Design se aplikuje při vývoji a testování systému. ECU jsou založeny na dsPIC Microchip zařízeních a programovány pomocí automaticky generované C kód.
