摘要：Electrical and control systems in missiles and nuclear reactors having critical sections are better implemented, if split into multiple number of tasks. These critical sections will have dissimilar priorities, timing deadlines and thus should be managed by a Real Time Operating System. In this article an embedded platform for industrial automated system is designed with multiple tasks. In order to manage the various tasks evaluated Priority based Preemptive Task Scheduling algorithm in MUCOS2 Real Time Operating System is used. Motor task is controlled by PI algorithm. When an interrupt is created, the corresponding task is executed thus response is obtained in few microseconds and the corresponding task output are displayed on the LCD. Consequently, with the sensor value, processing speed and timing constraints of the task scheduled, the automated system is functioning with rapid task execution context under multitasking environment.
