concept of homeostasis related to aging and disease? Provide examples to support your thinking. The older people get the less they are able to control their systems‚ such as their urinary system. When this happens they are more prone to diseases. 2. When we are dehydrated‚ we are thirsty and drink water. Is this the part of negative or positive feedback control systems? Explain your reasoning. This is negative feedback because when you are thirsty that results in low blood pressure. Once you drink

Root Locus Consider the closed loop transfer function: R(s) + - E(s) K 1 s(s+a) C(s) How do the poles of the closed-loop system change as a function of the gain K? The closed-loop transfer function is: The characteristic equation: Closed-loop poles: Root Locus When the gain is 0‚ the closed loop poles are the openloop poles Roots are real and distinct and for a positive a‚ in the left half of the complex plane. Two coincident poles (Critically damped response) Roots

Abstract— This paper presents the application of Fractional Order PID controller as a supplementary controller to improve the dynamics of Load Frequency Control in an interconnected system. FOPID is a PID controller whose derivative and integral orders are of fractional rather than integer. The extension of derivative and integration order from integer to fractional order provides more flexibility in the design of the controller there by improving the dynamics of the system. Using integral square

Feedforward control is “the control process used before operations begin‚ including policies‚ procedures‚ and rules designed to ensure the planned activities are carried out properly” (Bateman and Snell 555). The Conrads at this time are applying the feedforward control because they already have a vision of what their future business expansion
