null angle造句

Note that, as a consequence of the null angle modulation strategy, the position feedback is positive, that is, a sudden command to move right will produce an initial cart motion to the left followed by a move right to rebalance the pendulum.
The position of the cart x relative to track center is stabilized by slightly modulating the null angle ( the angle error that the control system tries to null ) by the position of the cart, that is, null angle = \ theta + k x where k is small.
