Control Block Description
ADDvantage-32 PLUS
4-92
4.61 RMP2
The RMP2 block provides a variable rate linear ramp with user programmable
smoothing. The purpose of this block is to provide a smooth reference from changing
setpoint values.
The difference between the RAMP block and RMP2 is the RND input. RAMP uses a
low-pass filter for rounding, causing a "J" curve. The RMP2 implements a rate of change
limit on the ramp, causing a uniform "S" curve.
FIGURE 4-61. RMP2 BLOCK
The RMP2 block can be divided internally into three components to aid in the
understanding of its operation. These components are a Ramp Change Block, a Rate of
Change Limit Block, and Additional Control I/O as can be seen in Figure 4-61A.
