What is the proportional integral and derivative control system response?
The proportional integral and derivative control system or PID control system consists of proportionsl, derivative and integral elements which gives a very efficient process control.
What happens to the damping when the settling time increases in a derivative error compensation?
increase
What type of current is induced in a dc generator when magnets are rotated?
The simple explanation as to why a change in the coil causes a change to the electric current is that the electric field and the magnetic field are the same field and they exist in a four dimensional quaternion space.Change in a quaternion space is four dimensional and when you take the derivative there is a real derivative d/dr=d/cdt and a vector derivative DelX= d/dr + Del = d/cdt + Id/dx + Jd/dy + Kd/dz.The answer to this question is the Quaternion four space derivative of the vector Electric Field, Ev.(d/dr + Del)Ev= -Del.Ev + dEv/dr + DelxEv = -Del.Ev + dBv/dt + DelxEvThe Quaternion Derivative is X=d/dr + Del = d/cdt + DelThe vector part of the derivative dB/dt + DelxEv is the answer to the question this can be transformed by introducing the coil with dA as the area and dC as the circumference:dBv/dt.dA + DelxEv.dA = AdB/dt + Integral loop Ev.dC
What is a derivative control?
Derivative control applied in control engineering, usually for the operation of control valves and its importance came during valve tuning. Derivative control is popularly known as anticipatory control. ( controller starts its control action, by anticipating the trend of present value (PV) of parameter.) Derivative control anticipates parameter values and and it will take control action to control the parameter with in set point. Eg: In a water heating system, water temperature is controlled by controlling steam valve opening. Let set point for water is 80°C, and derivative control will check the status of water temperature and if it is slowly increasing range ( may be due to some load change), controller will starts to control temperature by slowly closing steam valve. ( and vice versa) Actually this type control action just observe at control parameter values and initiates control action.
Does asphalt have glass in it?
It's not supposed to. Asphalt is a petroleum derivative (the stuff left after all the volatiles are removed), and there may or may not be rocks (crushed stone) added.
What is the derivative of -cosx?
-sinx
What is the derivative of x-cosx?
Take the derivative term by term. d/dx(X - cosX) = sin(X) ======
How do you take the derivative of a trig function?
Trig functions have their own special derivatives that you will have to memorize. For instance: the derivative of sinx is cosx. The derivative of cosx is -sinx The derivative of tanx is sec2x The derivative of cscx is -cscxcotx The derivative of secx is secxtanx The derivative of cotx is -csc2x
What is the derivative of sin x minus cos x?
d/dx(sinx-cosx)=cosx--sinx=cosx+sinx
What is the differentiation of sin x over 1 plus cosx?
The derivative is 1/(1 + cosx)
What is the derivative of the square root of 2 raised to the power of cos x?
The derivative of 2^x is 2^x * ln2 so the derivative of 2^cosx * ln2 multiplied by d/dx of cox, which is -sinx so the derivative of the inside function is -sinx * 2^cosx *ln2. As to the final question, using the chain rule, d/dx (2^cosx)^0.5 will equal half of (2^cosx)^-0.5 * -sinx * 2^cosx * ln2
