Open loop control systems are one in which Output have no effect on input.
Toaster,Washing machine and a Dc motor are the examples.
Consider an example of a dc motor, Due to voltage input it rotates a Shaft what happen if the load on shaft increases ???do you get the same output on same input??not possible because there is no such mechanism involved that will tell the motor to increase its input...that is no feedback mechanism involved in open loop system..thats why you will get a decrease in Output.

What is an open loop in control systems?
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
What are the example of a open loop con?
old systems
Examples of the open loop system?
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
What are the disadvantages of closed loop systems?
its costly than open loop system and bulky, too.
What is the definition of closed loop control system?
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
What are the examples for open and closed loop control systems with their block diagrams?
traffic signal,blind person,
Open loop and close loop system in injection moluld machine?
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
What is open loop and close loop system?
Q: What is the difference between 'Open Loop' and 'Closed Loop'? A: When the engine is first started, and rpm is above 400 rpm, the system goes into 'Open Loop' operation. In 'Open Loop', the ECM will ignore the signal from the Oxygen (O2) sensor and calculate the air/fuel ratio based on inputs from the coolant and MAF sensors, but mostly from a pre-programmed table in the memcal. The system will stay in 'Open Loop' until the following conditions are met: 1. The O2 sensor has varying voltage output, showing that it is hot enough to operate properly. (This depends on temperature) 2. The coolant sensor is above a specified temperature about 40oC/104oF. 3. A specific amount of time has elapsed after starting the engine. The specific values for the above conditions vary with different engines and are stored in the mem-cal. When these conditions are met, the system goes into 'Closed Loop' operation. In 'Closed Loop', the ECM will calculate the air/fuel ratio (injector on-time) based on the various sensors but mainly the O2 sensor. This allows the air/fuel ratio to stay very close to 14.7:1.
What is the definition of open loop process control?
it is when a control loop is open and processing
What is sensitivity of open loop control system?
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
What is an open loop system?
Open Loop control Systems have input, then the input is processed by various components like amplifiers, filters etc, then final out stage.The main difference between open loop and closed loop systems is that in open loop systems there is no feedback.
Advantages of open loop control system?
The open loop system is simple and economicaleasier to constructstable
