Control Systems The open loop transfer function of a unity feedback control system is given by G(s) = k/s(s+1). If gain k is increased to infinity, then damping ratio will tend to become zero unity 0.707 infinite zero unity 0.707 infinite ANSWER DOWNLOAD EXAMIANS APP
Control Systems A cascade of three linear time invariant systems is causal and unstable. From this we conclude that the majority are unstable and the majority are causal. each system in the cascade is individually caused and unstable. at least one system is causal and all systems are unstable. at least one system is unstable and at least one system is causal. the majority are unstable and the majority are causal. each system in the cascade is individually caused and unstable. at least one system is causal and all systems are unstable. at least one system is unstable and at least one system is causal.
