    Course Description
    In this course we discuss single-input, single-output control systems using feedback. We begin covering the elements in the control loop, their selection, and implementation. Then we study logic programming and its implementation on PLCs. Later, we study and analyze the PID controller, its modes, tuning parameters, and operation characteristics. Then stability in the control loop is discussed, and problems solved using direct substitution and frequency response methods. Finally, we cover general aspects of advanced control strategies (selected).

    COURSE LEARNING OUTCOMES ? SPECIFIC OUTCOMES OF INSTRUCTION
    By the end of the course the student will be able to:
    CO1. Identify and define the function of the constitutive elements of a control loop.
    CO2. Describe and select instrumentation to measure temperature, flow, level, and pressure.
    CO3. Size control valves for industrial process applications.
    CO4. Characterize, model, select, and tune PID controllers for industrial processes.
    CO5. Design ON/OFF control systems and implement them in PLCs.
    CO6. Design simple PID Control loops defining appropriate variables and instrument locations.
    CO7. Determine the effect of noise in a process or control loop signal by using frequency response analysis.
    CO8. Calculate the stability limit for a controller given a process dynamic model, and infer the effect of changes in process or controller parameters in such limit.
    CO9. Design and implement a control strategy to improve process performance (selected).
