1)the parameterization of the0controller0isC=X+MQ/Y-NQ。where N,M are right coprime factors of P,X,Y satisfy NX+MY=1,Q∈RH∞

2)According to the right coprime factorization of P, N=,M=,X=,Y=By the performance of the closed-loop system

N(0)[X(0)+M(0)Q(0)]=1 N(10j)[Y(10j)-N(10j)Q(10j)]=0，So take Q in the form Q(s)=x1+x2·1/s+1+x3·1/(x+

1)2

we can get the solution of Q。x1=,x2=,x3=,Q=Finally,the controller is C=

步驟:S=1-λ/λ代人 P(λ)=λ2/6λ2-5λ+1

X=-q2/r2 ,y=1+q1q2/r2 λ=1/s﹢1

N(S)=1/(s+1)2

M(s)=(s-1)(s-2)/(s+1)2 X(s)=19s-11/s+1Y(s)=s+6/s+1

C=X+MQ/Y-NQ

N(0)[X(0)+M(0)Q(0)]=1 N(10j)[Y(10j)-N(10j)Q(10j)]=0

Q(0)=6，Q(10j)=-94+70j Q(s)=x1+x2·1/s+1+x3·1/(x+

A control system is stable if the number of encirclements of the(-1,0)point by the GH plot is equal to the number of poles of GH with positive real parts.The direction of encirclement must be in a direction opposite to τs.GH is on open loop transfer function.τs is open right half of s-plane.一個控制系統(tǒng)是穩(wěn)定的數(shù)量是否包圍的(1,0)點的GH圖的數(shù)量相等的兩極與積極的真實部分GH。被包圍的方向都必須在一個τs的相反方向。

“GH”是在開環(huán)傳遞函數(shù)上。τs在s-plane的右半平面開放。

二．The process of designing a control system generally involves many steps.A typical scenario is as follows:

1.Study the system to be controlled and decide what types of sensors and actuators will be used and where they will be placed.2.Model the resulting system to be controlled.3.Simplify the model if necessary so that it is tractable.4.Analyze the resulting model;determine its properties.5.Decide on performance specifications.6.Decide on the type of controller to be used.7.Design a controller to meet the specs, if possible;if not, modify the specs or generalize the type of controller sought.8.Simulate the resulting controlled system, either on a computer or in a pilot plant.9.Repeat from step 1 if necessary.10.Choose hardware and software and implement the controller.11.Tune the controller on-line if necessary.r．reference or command inputvsensor outputuactuating signal, plant inputdexternal disturbanceyplant output and measured signaln．sensor noise

歐姆定律

Ohm’s law states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.法拉第定律

Faraday’s states that the voltage across the inductor is proportional to the rate of change with time of the current through the inductor.基爾霍夫第一定律

Kirchhoff’s first law states that the algebraic sum of the voltages around a closed loop is 0,or,in any closed loop, sum of the voltage rises must equal the sum of voltage drops.運放

The first law states that in normal op-amp circuits we may assume that the voltage difference between the input terminals is zero, that is, U+=U-.The second law states that in normal op-amp circuits both of the input currents may be assumed to be zero: I+=I-電路理論 theory of circuit
