在控制系统中，步进电机的转子位置信息的获取通常是通过位置传感器来实现的。

Weaknesses: Defensively Tucker could stand to improve on his intensity … Doesn't seem to possess great anticipation skills nor the awareness to play the passing lanes … Ball handling, while improved, still isn't great … Perimeter shooting remains prone to streakiness … Not a great shooter coming off screens … Solid three point shooter when his feet are set but struggles to hit with regularity due in part to his slow release … Despite being a great athlete, Tucker rarely explodes off the dribble due to his average first step … Doesn't always use the mid-range jumper to his advantage, often he'll slash to the basket or shoot the three … From a position standpoint there is concern about what position he will play in the NBA … While blessed with athleticism, he may struggle to shoot consistently enough to play shooting guard and his height might be a detriment at small forward … While his game has progressed considerably over the past 5 years, one has to wonder how much more he can improve … Below average free throw shooting limits his ability to take full advantage of the contact he creates … BY Matthew Maurer

弱点：Tucker应坚持提高他在防守中的紧张程度。没有让大家看到令人期待的技能。边缘的投射仍然有些忧虑，犹豫。持球能力在提高，但仍然不是很好。。。三秒区也没意识到传球。在脱离掩护后不是名很好的射手。定点时稳定的3分射手。但他仍尽力使自己的得分更加稳定，有规律。很大程度是因为他的慢热。而且作为优秀的运动员，Tucker很少突然运球加速，因为他启动速度不是很快。。。他不总用他中距离跳投的优势，他经常slash to the basket或投射3分。。。他现在很担心忧虑自己将会在NBA中担任什么位置。。。当他有幸得到良好的运动热情，他可能去担当得分后卫而且他的身高不利于打SF。当他过去5年已经有了相当大的进步，人们都对他还有多大的提高空间感到疑问。他低于平均水准的罚球能力限制了他利用身体优势造对手犯规然后得分这种战术的实施。
