Abstract-Transient response such as ringing in a control system can be reduced or removed by velocity feedback. It is a useful control technique that should be covered in the relevant engineering laboratory courses. We developed velocity feedback experiments using two different low cost technologies, viz., operational amplifiers and microcontrollers. These experiments can be easily integrated into laboratory courses on feedback control systems or microcontroller applications. The intent of developing these experiments was to illustrate the ringing problem and to offer effective, low cost solutions for removing such problem. In this paper the pedagogical approach for these velocity feedback experiments was described. The advantages and disadvantages of the two different implementation of velocity feedback were discussed also.

“…However, with the proliferation of distance learning degree programs, there have been ongoing efforts to figure out how to enable hands-on lab experience remotely [1][2][3][4][10][11][12][13]. Many online engineering programs failed to obtain ABET accreditation [8] due to lack of hands-on laboratories.…”

“…This system is portable plug-and-play and robust but at a very high cost point greater than $1k, and it requires Matlab. Another proposal was a system based on off-the-shelf microcontroller board dsPIC and discrete drivers and interface electronics [10]. This solution does not require Matlab, but involves assembly and do not meet the low cost threshold.…”

Lack of remote access to engineering laboratory systems has prevented distance learning from fulfilling the accreditation requirements of hands-on design and implementation experience. Although there have been solutions developed around remote and virtual laboratories, these solutions do not fulfill the simultaneous requirements of being portable, plug-and-play, low cost, and commercially available. In this paper, we propose a product oriented solution of a low-cost hardware lab system that every student can own and conduct their laboratory experiments at any location. We introduce a control system lab platform called servo-in-a-box, which is an integrated electro-mechanical servo system, complete with DC motor, sensor, power driver, USB interface, and software. This servo-in-a-box enables many undergraduate control engineering students to conduct PID hardware control lab remotely and individually, while meeting the hands-on learning objectives associated with a traditional on-campus laboratory.

“…Robust hardware will have a better return on investment because it will see many years of use before needing replacement. Aside from hardware failures, it's also frustrating to students when something in the implementation of an experiment doesn't go as planned, and there is no obvious logical reason [13]. The hardware, software, and implementation procedure all need to be robust enough that when things inevitable do go wrong, there is an obvious logical reason, and instructors can work with students to get them past such setbacks.…”
