Page 12: Chapter 1 Overview
CHAPTER 1 OVERVIEW This manual describes the process control instructions equipped for the CPU module. Features The process control instructions have the following features. (1) Use of floating-point data Capable of handling floating-point type real number data, the instructions can perform wide-range and accurate operations.
Page 13 (3) Free combination of process control instructions for application to a wide range of control As an option, a process control instruction can be inserted in a loop that links process control instructions. Add the square root operation instruction (S.SQR) to perform the square root operation of an input signal to provide an output signal as shown below.
Page 14 (5) PID algorithm using a velocity type incomplete differential format Partial differential has the following advantages over the complete differential format. (a) The differential gain is 1/ and the limit value can be set. (b) The output contains time amplitude, so the system actually responds to the operation edge so the derivative operation makes the movement valid.
Page 15: Pid Control Overview
PID Control Overview PID control is applied to the process control of flow rate, speed, air volume, temperature, tension, compounding or like. In the following application, a value of a control target system can be kept at a set value with PID control. Subdivided (micro-blocked) processings Process control instructions of PID control...
Page 16: Pid Control Details
PID Control Details This section explains "proportional operation", "integral operation" and "derivative operation" performed for PID control using the process control instructions. 1.4.1 Proportional operation (P operation) This section explains the control method using proportional operation. (1) Proportional operation is the action that compares the deviation (DV, difference between the set value and the process value) to find the manipulated value (MV).
Page 17: Integral Operation (I Operation)
1.4.2 Integral operation (I operation) This section explains the control method using integral operation. (1) Integral operation is the operation that continuously changes the manipulated value to eliminate deviation when there is deviation. This operation can eliminate the offset that occurs during control performed by a proportional operation. (2) The time required for adjusting the manipulated value of the integral operation to the manipulated value of the proportional operation after the deviation is detected is called integral time (T (a) Increasing the integral time decreases the effect of integration.
Page 18: Derivative Operation (D Operation)
1.4.3 Derivative operation (D operation) This section explains the control method using the derivative operation. (1) The derivative operation is an operation that adds the proportional manipulated value to the change speed to eliminate deviation when a deviation has occurred. The derivative operation can prevent large changes in the object control from disturbances.
Page 19: Pid Operation
1.4.4 PID operation This section explains the control operation using combinations of proportional operation (P operation), integral operation (I operation), and derivative operation (D operation). (1) The PID operation controls the calculated manipulated value using (P + I + D) operation. (2) The PID operation in the case of a step response with a constant deviation will be as follows.
