How do you find the gains for a PI controller with a first order plant and 2nd order low pass filter?
How can analytically work out the gains knowing the required bandwidth and damping? The plant to be controlled is first order. The low pass filter is 2nd order in the feedback path.

Voltage drop on amplifier signal after LED switches on
Circuit above shows my design for amplifying PIR sensor signal, which I then feed to Arduino and based off this signal I switch a LED on.
Both, the LED and PIR sensor, are on the same voltage rail (9V)...

Complementary filter in MPU_6050 is giving me the wrong answer when the system is accelerating
So I am using a complementary filter to find the attitude in my quadcopter, doing the following
$$\text{angle} = 0.98\cdot (\text{angle}+\text{dt}\cdot \text{angle_rate})+0.02\cdot \text{...

What is the output of a signal in time domain that passed through a High Pass Filter with simple transfer function
If a signal function $ U(t) = 25 – (5 – t)^2$ is passed through a high pass filter with transfer function $\frac{s}{s + ω}$. what is the output signal Y(t). I know that the transfer function $H(s) = \...

How to choose order and cut-off frequency for low-pass Butterworth filter?
When using IMU data (accelerations and angular velocities), many papers use a 4th order low-pass butterworth filter with a cutoff frequency of 5 Hz. However, none of them really justify why those ...

High Pass Filter Design from Transfer Function
I need to design an active high pass filter circuit that implements the following transfer function:
$$G(s)= 4.15\times\dfrac{s+530}{s+2200}$$
where, $K = 4.15$, Pole @ 2200 rad/s and Zero @ 530 rad/...
