Basis Function Parameterization In a gain-scheduled controller, the scheduled gains are functions of the scheduling variables,σ. For example, a gain-scheduled PI controller has the form: C(s,σ)=Kp(σ)+Ki(σ)s. Tuning this controller requires determining the functional formsKp(σ) andKi(σ)...
Use zpk to create zero-pole-gain models, or to convert dynamic system models to zero-pole-gain form. Zero-pole-gain models are a representation of transfer functions in factorized form. For example, consider the following continuous-time SISO transfer function: G(s)=s2−3s−4s2+5s+6 G...
“sensitivity feedback system”, and it acted to compensate for changes in both altitude and speed (Paddison, 1982). Thus the flight of a Talos exhibited a rudimentary form of gain scheduling at the outset, followed by a scheduling approach that is now quite standard, and finally what might...
This paper considers the problem of stabilizing a given linear time-invariant plant with a specified damping ratio and damped natural frequency using a constant gain compensator. We show the problem to be solved can be decomposed into two sub-problems. Thereafter, an appropriately generalized version...
8 proposed the use of two interleaved KY converters, and16 combined a KY converter interleaved with a conventional buck converter to form a buck-boost converter for stepping up the output voltage. While high voltage gain can be achieved by these converters, they face limitations when operating ...
Thus, quantitative model comparisons corroborated the presence of urgency with time-dependency in the decision process under deadline. Using the closed-form function for the urgency signal in the above model fits (equation 4), we also approximated the optimal, reward-maximizing shape of time-...

You can also implement matrix-valued gain schedules Simulink. A matrix-valued gain schedule takes one or more scheduling variables and returns a matrix rather than a scalar value. For instance, suppose that you want to implement a time-varying LQG controller of the form: ...
If the observer you are tuning does not allow reconfiguration to the form shown in Figure 10.19, the observer can still be tuned by selecting the gain margin. First the system must be configured so that the control loop is closed on the sensed signal, since this method will temporarily gener...
If we assume that a single vibrational frequency ΩR of silica molecules is involved in the Raman process, hR(t) can be written in the form [16] (2.3.40)hR(t)=τ1-2+τ2-2τ1exp(-t/τ2)sin(t/τ1), where τ1=1/ΩR and τ2 is the damping time of vibrations. In practice...
