This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Continuous Control System”.
1. Which of the following objective is to maintain process performance at a certain level or within a given tolerance of that band?
a) Proprietary Control
b) Distributed Control
c) Regulatory Control
d) Forensic Control
View Answer
Explanation: The objective of Regulatory Control is to maintain process performance at a certain level or within a given tolerance of that band of that level. This is applicable when performance attribute is a measure of product quality.
2. Which is defined as the performance measure of the process?
a) Variable performance
b) Index of Performance
c) Process Performance
d) Subject of Performance
View Answer
Explanation: Index of Performance is defined as the performance measure of the process. It is a measure of the quality of the process and will be calculated based on the several output variables of the process.
3. Which control elements sense the presence of the disturbance and take corrective actions by adjusting process parameter?
a) Adaptive Control
b) Frontend Control
c) Bead forward Control
d) Feed forward Control
View Answer
Explanation: The control technique in which the control elements sense the presence of the disturbance and take corrective actions by adjusting process parameter is known as feed forward control technique. The effect of disturbance will be eliminated in advance.
4. Regulatory and feed forward are more closely associated with discrete industries rather than process industries.
a) True
b) False
View Answer
Explanation: Regulatory and feed forward are more closely associated with process industries rather than discrete product manufacturing industries. They are more commonly used in all processes in manufacturing concepts rather than discrete product manufacturing industries.
5. Which control technique exhibits well defined index of performance and is implemented when the index of performance and process parameters are known?
a) Feed forward Control
b) Adaptive Control
c) Steady State Optimization
d) Dynamic optimization
View Answer
Explanation: The control technique which exhibits well defined index of performance and is implemented when the index of performance and process parameters are known is the steady state optimization.
6. Which is designed to make adjustments in the process parameters to drive the process to an optimized state?
a) Parametric Logarithm
b) Arithmetic Logarithm
c) Control Algorithm
d) Boolean Variable
View Answer
Explanation: In order to drive the process to an optimized state, Control Algorithm will be designed to make adjustments in the process parameters. Various mathematical programming can also be used while optimizing the process.
7. Which control combines the feedback control and optimal control by measuring the suitable process variables?
a) Mixed State Control
b) Adaptive Control
c) Flexible Control
d) Linear control
View Answer
Explanation: The Control technique which combines the feedback control and optimal control by measuring the suitable process variables is known as adaptive control. It has a unique capability to be applicable in the time varying environment.
8. Steady State optimal technique usually operates on closed loop system.
a) True
b) False
View Answer
Explanation: Steady State optimal technique usually operates on an open loop system. When there is no disturbance between the process parameter and the variables, it works successfully. It cannot be operated for closed loop systems.
9. Which of the following is not the function of an adaptive control system?
a) Identification
b) Reduction
c) Decision
d) Modification
View Answer
Explanation: Reduction is not a typical function of an adaptive control system. Identification, Decision and Modification are the three basic functions of an adaptive control system. An adaptive control system is used to interact with the system in an effective manner.
10. Which function of the adaptive control system does the current value of the index of performance is determined?
a) Modification
b) Decision
c) Identification
d) Friction
View Answer
Explanation: In an adaptive control system, identification function determines the current value of the index of performance. It must be accomplished more or less continuously over time during operation.
12. Which function of an adaptive control system is implemented by the adaptive system’s programmed algorithm?
a) Identification
b) Decision
c) Reversion
d) Modification
View Answer
Explanation: The Decision of an adaptive control system is implemented by the adaptive system’s programmed algorithm. It will be change either one or two input parameters. Identification, Decision and Modification are not implemented by the adaptive system’s programmed algorithm.
13. Which function of an adaptive control system is concerned with the physical changes in the system?
a) Modification
b) Identification
c) Moderation
d) Decision
View Answer
Explanation: The function of an adaptive control system in which the physical changes in the system is usually done is known as modification. Its primary function is to implement the decision.
14. Which type of machining involves the changes in process variables are used to affect control over process parameters?
a) Static Machining
b) Adaptive Control Machining
c) Process Machining
d) Additive Machining
View Answer
Explanation: The type of machining in which changes in process variables are used to affect control over process parameters is known as adaptive control machining. It is an application of adaptive control.
15. Which type of strategy can be used when the decision function cannot be sufficiently defined?
a) Row off Strategy
b) On-Line Search Strategies
c) Row in Strategy
d) Robust Strategy
View Answer
Explanation: The type of strategy which can be used when the decision function cannot be sufficiently defined is the on-line strategy. These include a variety of schemes to explore the effects of process parameters.
16. Which of the following is a evolving specialized technique combining control system and computer science?
a) Backward Loop Strategy
b) Artificial Intelligence
c) Forward Loop Strategy
d) Mixed Strategy
View Answer
Explanation: Artificial Intelligence methods for process control are one of the evolving specialized techniques combining control system and computer science. Backward Loop Strategy, Forward Loop Strategy and Mixed Strategy techniques are not based on combining control system and computer science.
