This paper gives the time domain integral constraints of the feedback control systems tracking error that arise from the presence of stable zeros on or near the jω-axis, which shows that for a linear time invariant system, in order to guarantee the stability of the closed-loop system, the time domain integral constraints must be satisfied by the tracking error.

Some conclusions of their research were tested.In their study,only intrapersonal constraints and intrinsic motivation had significant relationship,while the extrinsic motivation and constraints had no significant relationship.

Alexandris和Tsorbatzoudis的研究认为，只有内部约束与内在动机有显著的关系；外在动机与约束因素之间没有显著的关系；内在动机与体育参与频率之间是显著的正向关系。

The objective function of the QP problem is a quadratic function which is an approximation of the Lagrangian function of the constrained problem and the constraints of the QP problem are linear approximation of the constraints of the constrained problem.
