In discrete-time control theory, the dead-beat control problem consists of finding what input signal must be applied to a system in order to bring the output to the steady state in the smallest number of time steps. For nonlinear systems, dead beat control is an open research problem. (See Nesic reference below). Dead beat controllers are often used in process control due to their good dynamic properties. They are a classical feedback controller where the control gains are set using a table based on the plant system order and normalized natural frequency.

- 無差拍控制（dead-beat control）是離散控制理論的一種問題，是針對特定系統，要找到可以在最短時間內讓輸出進入穩態的輸入信號。 可以證明在N階的線性系統中，若系統為零可控（null controllable，是指可以利用特定輸入使狀態變為0），其最少的步數不會超過N步（依初始條件而不同）。 解法是用反饋的方式，使閉迴路轉移函數的極點都在z平面的原點（有關z平面及轉移函數的細節，請參考Z轉換）。因此線性系統的例子很容易找到解。因此一個極點都在z平面的閉迴路轉移函數有時也會稱為無差拍轉移函數（dead beat transfer function）。 非線性系統的無差拍控制是一個仍在研究中的問題（可以參考以下Nesic的參考資料）。 無差拍控制器因為其動態特性良好，常用在過程控制中。此控制器是典型的回控控制器，其控制增益是依系統階數及正規化自然頻率的表來設定。 無差拍控制的特性如下： 1.

| - In discrete-time control theory, the dead-beat control problem consists of finding what input signal must be applied to a system in order to bring the output to the steady state in the smallest number of time steps. For an Nth-order linear system it can be shown that this minimum number of steps will be at most N (depending on the initial condition), provided that the system is null controllable (that it can be brought to state zero by some input). The solution is to apply feedback such that all poles of the closed-loop transfer function are at the origin of the z-plane. (For more information about transfer functions and the z-plane see z-transform). Therefore the linear case is easy to solve. By extension, a closed loop transfer function which has all poles of the transfer function at the origin is sometimes called a dead beat transfer function. For nonlinear systems, dead beat control is an open research problem. (See Nesic reference below). Dead beat controllers are often used in process control due to their good dynamic properties. They are a classical feedback controller where the control gains are set using a table based on the plant system order and normalized natural frequency. The deadbeat response has the following characteristics: 1.
* Zero steady-state error 2.
* Minimum rise time 3.
* Minimum settling time 4.
* Less than 2% overshoot/undershoot 5.
* Very high control signal output (en)
