An embedded control system (ECS) is a delicate system that provides specific control function to a larger system where the ECS is embedded. With the variety of control objectives, design of embedded control systems can be very different, and generally result in ad hoc designs. This paper proposes a systematic approach for embedded control systems; in particular, this paper addresses the three most important issues: (1) functional specification and modeling by Statecharts, (2) modular design and implementation of software and hardware for: sensor, control algorithm, actuator and user interface, and (3) verification of the final implementation. This paper presents a systematic approach to embedded control systems in four steps by gathering associated methods reported in the literature which are otherwise scattered. For illustration, this paper takes an intelligent temperature controller of heating ventilation and air. conditioning (HVAC) system to highlight the three design stages of product development for embedded control systems.
