control systems

The output of a photodiode is used as the feedback signal of a laser intensity control loop. The controller currently implements PI control, and the laser together with the optical path forms the plant transfer function. When a step change is applied to the system, the photodiode output shows...

Greetings everyone, Recently i have the final year project of heater load control using zero crossing method. The heater capacity is 2300 kW, and i decrease the scale into 1/3 (760 kW). The heater supply voltage is 690V. It's full capacity is divided into 5 branches and each branches are...

Every real-world project comprises interconnected systems. Can you suggest any courses that provide insights into comprehending systems and their role as integral building blocks in projects? I am an electronics engineer seeking relevant recommendations.

Hi! Below is the open loop output current to control plot for a CLLC resonant converter(obtained using AC sweep in PSIM) . As you can see the gain curve never crosses the 0 dB line and the phase margin is inf, hence the open loop system is always stable. Note: switching frequency is around...

Hello, I have a transfer function of an active suspension system of a quarter of a vehicle, they ask me to calculate a controller from the Bode diagram that complies with overshoot of 33% and settling time 1. I have the problem that the margin of phase gives infinity, if someone could guide me I...

Hello guys i have a question. I want to simulate on simulink this example. and find the open loop responces from the real system and observer. On this examples says that we must use "strong u(t) to shake the things up" :P Does enyone know what kink of input is this? I use step responce and...

Hi everyone! I'm Buse. I'm trying to control a motor speed for a personal project. You can find the schematic of the circuit I found on a book. This circuit works with only the PID parts contrcuted. My problem start when I add the other parts. For example, U1 opamp (top left) is supposed to...
