A Rate Limiter controls the rate of change of variable and is used to avoid abrupt change of values thatcauses transient and jerky operation. Rate Limiter is generally used to generate a smooth speed profile while changing from one speed range to another speed range. The rate of change of output remains within the specified limit whether the output is increasing or decreasing with respect to time. The output slope is configured by two parameters—rate count and slew count.
