A multi-input and multi-output optimal controller for stochastic systems with time-varying dynamics is developed. The system to be controlled is described using a multi-input and multi-output time-varying autoregressive moving average model with multiple delays. The controller minimises a generalised minimum variance cost functional that is the sum of quadratic output tracking error variances a...
This paper studies one example of dynamic optimisation of systems subject to hydraulic transportation delays. Properly taking into account the variability of the delay in optimisation is a challenging problem, of importance in several applications. While stationary conditions have been derived in earlier works, here we investigate practical numerical aspects and propose a direct resolution meth...
Delays between user input and the system’s reaction in control tasks have been shown to have a detrimental effect on performance. This is often accompanied by increases in self-reported workload. In the current work, we sought to identify physiological measures that correlate with pilot workload in a conceptual aerial vehicle that suffered from varying time delays between control input and vehi...
Control of the inner engine torque of a combustion engine is very crucial for the overall performance of a dynamical combustion engine test bench. The main problem thereby is the usually unknown system behavior of the combustion engine, the time delay of the accelerator actuator which is used to control the combustion engine. In general the combustion engine is mounted on a combustion engine te...
a1 AbstractWe describe an analog VLSI circuit that computes the time delay between an arbitrary input signal and its delayed version. Versions of this circuit will be used as the basic computational elements for human auditory localization models in both the horizontal and vertical directions. Since the circuit uses subthreshold CMOS circuitry, chip measurements show that delays ranging over fi...
The paper investigates the robust control for uncertain Takagi–Sugeno (T–S) fuzzy systems with time-varying state and input delays. Delay-dependent stabilization criterion is proposed to guarantee the asymptotic stabilization of fuzzy systems with parametric uncertainties. The result of [Lee HJ, Park JB, Joo YH. Robust control for uncertain Takagi– Sugeno fuzzy systems with time-varying input d...
Consensus and coordination of multiple teleoperated agents has been a control topic of growing interest over the last decade due, in part, to its many potential applications and related complex challenges. One of these challenges is to guarantee stability and motion coordination in the presence of inherent communication and input delays as well as system nonlinearities in the multi-agent system...
We consider a reflected Lévy process without negative jumps, starting at the origin. When the reflected process first upcrosses level K, a timer is activated. D time units later the timer expires, and the Lévy exponent of the Lévy process is changed. As soon as the process hits zero again, the Lévy exponent reverses to the original function. If the process has reached the origin before the time...
The partially observed risk-sensitive optimal stochastic control of a system with multiple time-delays in input, which minimizes the expected value of an exponential cost criterion, is considered. The change of measure technique is used to obtain the sufficient statistics of the cost criterion given the measurement history, which is called the information state. The information state helps to c...
Stability and L2 (l2)-gain analysis of linear (continuous-time and discrete-time) systems with uncertain bounded time-varying delays possessing non-zero nominal values and norm-bounded uncertainties. The delay derivatives (in the continuous-time) are not assumed to be less than q < 1. An input-output approach is applied by introducing a new input-output model, which leads to effective frequency...
