As compared to closed loop system an open loop control system is more stable as all its roots are in left half of s plane only, but it less accurate since there is no feedback to measure the output value and compare it with the input value.

Closed Loop Control System vs Open Loop Control System
Closed loop control system is a type of control system where the output of the system is fed back to the input, and the input is adjusted accordingly to achieve the desired output. On the other hand, an open loop control system is a type of control system where the output of the system is not fed back to the input, and the input is not adjusted based on the output.
Speed and Bandwidth Comparison
Speed and bandwidth are two important parameters that determine the performance of a control system. The speed of a control system refers to how fast it can respond to changes in the input or disturbances in the system. The bandwidth of a control system refers to the range of frequencies over which the system can operate.
In the case of closed loop control system, since the output is fed back to the input and the input is adjusted accordingly, the system is faster and has more bandwidth. This is because the feedback loop allows the system to respond quickly to changes in the input or disturbances in the system, and also allows the system to operate over a wider range of frequencies.
In contrast, in the case of an open loop control system, since there is no feedback loop, the system is slower and has less bandwidth. This is because the system cannot respond quickly to changes in the input or disturbances in the system, and also has a limited range of frequencies over which it can operate.
Conclusion
In summary, closed loop control systems are faster and have more bandwidth as compared to open loop control systems. This is because the feedback loop in closed loop control systems allows the system to respond quickly to changes in the input or disturbances in the system, and also allows the system to operate over a wider range of frequencies.
