A typical uncertainty structure of a characteristic polynomial is P(s)=A(s)Q(s)+B(s) with A(s) and B(s) fixed and Q(s) uncertain. In robust controller design Q(s) may be a controller numerator or denominator polynomial; an example is the PID controll

Controllers are usually implemented in a digital computer. Figure 11.1 shows a single-loop sampled-data control system with c z (z) representing the z-transfer function of the digital controller, and (1 - e - s T s as the transfer function of the hol

The family of characteristic polynomials of a SISO-PID loop with N representative plant operating conditions is P i = Ai(s)(K I ; + Kps + K D s2) + B i (s), i = 1,2…N. A basic task of robust control design is to find the set of all parameters K I ,

Solving nonlinear algebraic systems of equations is one of the main problems encountered when investigating uncertain polynomials or transfer functions. A basic task is the elimination of variables to generate the so-called univariate polynomial. Thi

When applying the parameter space design method of the preceding chapter, regions of controller coefficients are first determined, guaranteeing simultaneous Γ-stability of a finite plant family. The design method of [111,110], which will be presente

With Chapter 11 we are entering into Part IV of this book, the part that deals with design. For an uncertain closed-loop characteristic polynomial p(s, q, k) we want to find a k = k0 such that the polynomial p(s, q, k0) is Γ-stable for all q ∈ Q.

The examples of Chapter 1 have in common that the plant is insufficiently damped or even unstable in its operating domain Q. Thus, a primary task of a control system is stabilization with sufficient damping for all q ⋲ Q. Since eigenvalues cannot b

In Chapters 8 and 9, the stability of polynomial families $$ P\left( {s,Q} \right)\; = \;\left\{ {p\left( {s,q} \right)\;|\;q\; \in \;Q} \right\}$$ (1) with p(s, q) = ao(4) + ai(4)s +… + an(q)sn and q, E [4,; 4:], i = 1, 2,…, € was investigated

It is well known that a linear time-invariant system is stable if the roots of its characteristic polynomial have a negative real part. In short we speak of “stability of a polynomial”.
